* fix track_max_mem in forward_batch_wo_cache_flash_attn_train * remove unnecessary Adam(W) optimizer tensors. reduces optimizer memory overhead from 7*modelsize to 2*modelsize. additionally allows to optimize models with more than 2^31 parameters by replacing int with int64_t. bumps training checkpoint file version, but old checkpoints can still be read. new version with less tensors is saved. * add gradient clipping to AdamW * Fix reset of unused g->nodes and g->grads to NULL * implement gradient checkpointing for training reduces memory overhead from O(n_layer) to O(sqrt(n_layer)) as explained in readme of https://github.com/cybertronai/gradient-checkpointing * remove unused compute buffer 3 * add and use function ggml_build_backward_expand to avoid stack overflows with large maximum number of nodes GGML_API void ggml_build_backward_expand(struct ggml_context * ctx, struct ggml_cgraph * gf, struct ggml_cgraph * gb, bool keep); * change AdamW decay parameter to work like the torch AdamW decay parameter It is now relative to Adam learning rate `alpha*sched`. Before that it was relative to `sched` only. `alpha` being the maximum learning rate and `sched` being a scaling parameter in [0..1] * change default AdamW weight decay parameter used in training to 0.1 as used in nanoGPT * change default AdamW weight decay parameter defined in ggml to 0.0, making Adam default instead of AdamW btw: the default weight decay parameter for torch.optim.AdamW is 0.01 * bug fixes for cross entropy loss ggml_cross_entropy_loss: sums where not correctly added in workload of each thread ggml_cross_entropy_loss_back: simplify backward process, reducing numerical issues guard usage of exp f16 lookup in cross entropy by #define GGML_CROSS_ENTROPY_EXP_FP16 cross entropy loss is only used once during training, but it is quite sensitive to numerical errors introduced by exp-f16-lookup. so exp-f16-lookup for cross entropy loss is disabled by default, trading better gradients for very slightly worse runtime performance. * fix test-grad0 for cross_entropy_loss the second argument to cross_entropy_loss must sum up to 1 for each row * fix test-grad0 for soft_max dont use only sum as aggregation, because sum of softmax is always 1 -> finite differences should not work instead use sum(log(soft_max()*(1-eps)+eps)); use eps to avoid log(0) * improve finite differences of test-grad0 by using double instead of float * change cross_entropy_loss to output average over all rows this helps keeping the loss and gradients in a sane range * improve gradient checkpointing sqrt(n_layers) is only the best checkpoint step when mem size of checkpoints and mem size of layers are equal. since layers require more memory than the single-tensor-checkpoint we use, the optimal values are compute different: ``` given: n, u, v objective: minimize(a*u+b*v) where a*b=n, a>0, b>0 b=n/a minimize(a*u+v*n/a) diff(a*u+v*n/a, a) = u - (v*n/a)/a diff(a*u+v*n/a, a) == 0 u - (v*n/a)/a == 0 u == v*n/(a*a) u*a*a = v*n a*a = v*n/u a = sqrt(n*v/u) ``` this change results in more checkpoints, requiring less layers to store between checkpoints, overall improving memory usage. * disable gradient checkpointing debug output * llama : fix rope usage in train-text-from-scratch after ChatGLM change * add more training parameters: --enable-restart N Only for Adam optimizer. Enable restarts of cos-decay --disable-restart N Only for Adam optimizer. Disable restarts of cos-decay --opt-past N Number of optimization iterations to track for delta convergence test. Disabled when zero. --opt-delta N Maximum delta for delta convergence test. Disabled when <= zero. --opt-max-no-improvement N Maximum number of optimization iterations with no improvement. Disabled when <= zero. --adam-epsf N AdamW epsilon for convergence test. Disabled when <= zero. --adam-min-alpha N Adam minimum learning rate alpha, usually 0.1 * alpha * replace memcpy with reshape operation so that the graph is not cut at the input this makes it possible to store other values into the input tensor and then simply recompute the graph without rebuilding it * remove unused function argument from get_example_targets_batch * measure and print total training time * add optimization callback to ggml_opt_resume_g this callback is called before each iteration with custom data and pointer to learning schedule parameter (only used in Adam(W)). can be used for dynamic learning schedule and setting input data for batches before each iteration * use optimization callback in training allows dynamic learning schedule and different batch data for each iteration without relying on low n_iter and high n_examples parameters reduces runtime by avoiding restart of optimization function and improves training convergence by providing a different batch for each iteration * add minimum number of tensor dimensions to apply weight decay (default 2) this allows to not apply weight decay to bias parameters * rename training parameter cos-decay-alpha to cos-decay-min and clarify that adam-min-alpha also applies to warmup * fix increase of model.train_samples and model.train_tokens now that each optimizer iteration gets its own batch we need to multiply by number of opt iterations * change sampling parameters for prediction after training to defaults of common.h and clarify what is context for prediction and what are generated tokens * tighten abs error bounds for cross_entropy_loss in test-grad0 * add conditional compilation of using F16 exp in flash attention uncomment `// #define GGML_FLASH_ATTN_EXP_FP16` to enable usage of f16 exp in flash attention * tighten abs error bounds for flash_attn in test-grad0 * tighten abs error bounds for sqrt in test-grad0 * remove out-commented vectorized code of opt_adam the vectorized code might be bit faster for low number of parameters, but it had a big memory usage overhead * ggml : update ggml_rms_norm_back with configurable eps * llama training : fix ggml_rms_norm_back calls to pass configurable eps * remove trailing whitespace * add train function using automatic gradient checkpointing backward pass and allocator * in train function replace add_inplace by regular add because using add_inplace seems to result in different gradients * don't use allocate hash_map on context because the context has no_alloc=True when using memory allocator resulting in NULL data pointers * correctly clone reshape and permute operations by also cloning tensor->nb values * fix variable name and add missing type cast * terminate recursive tensor cloning when reaching tensor without src tensors * correctly clone view tensors by setting data pointers without this the checkpointing would only work when being used together with memory allocator * fix variable names * swap arguments to commutative ops to be the same as in `forward_batch_wo_cache_flash_attn` * add input tensors as checkpoints so that recursive tensor cloning of gradient checkpointing terminates on input tensors * fix variable name and add missing boolean negation * make sure some tensors are not reallocated by inserting new temporary nodes depending on them: output and parameter gradient tensors need to be available at the end of the graph execution parameter gradient tensors also need to be available before the graph execution because they are set to zero before each optimizer iteration checkpoint tensors are allocated all together to reduce memory allocator fragmentation afterwards, in addition to the temporary nodes, we also need to reset the temporary leafs * fix ASSERT to work with zero layers * add training options whether to use allocator and/or unified training function * integrate unified training function which may use memory allocator the unified training function also supports arguments whether to use flash attention and/or gradient checkpointing * format name of cloned tensors with " (clone)" suffix * set names for tensors in unified train function for easier debugging * allocate graph on context using ggml_new_graph * remove handwritten training functions * remove unused training parameters "use_scratch" and "use_unified" * remove trailing whitespace * remove unused train params: mem_compute1_gb & mem_compute2_gb mem_compute_gb is used for compute when automatic memory allocator is not enabled, otherwise it can be very small to only hold the tensor definitions mem_compute0_gb is used for automatic memory allocator (as long as measurement of max required size is not implemented) * remove unused forward_batch function * add debug asserts in ggml_allocr_alloc to some common pitfalls when using this function directly * only use ggml_allocr_alloc when tensor has NULL data and is no view * fix test when to create temporary backward graph temporary backward graph is only necessary when using checkpointing * fix memory "leak" in optimizers each iteration a new cplan with new memory for work data was allocated. now cplan creation only happens at the start of optimization, with each iteration reusing the cplan and its work data. * reverse order of for loop in ggml_build_backward_expand to save memory when using gradient checkpointing and allocator with this loop order gradient checkpointing with allocator on 16 layer model saves 13% memory; 2 layer memory it saves 2% memory. the computation results are the same * add missing lctx argument to get_example_targets_batch * implement llama model file saving using gguf checkpoint loading and saving disabled, to be replaced by loading and saving via gguf * implement loading/saving of checkpointing files using GGUF * bug fixes * add checkpoint file version for future compatibility * update readme with gguf filenames * save & load opt->just_initialized value * add first draft for checkpoint conversion script * add gguf arch and ftype * save opt parameter counter as uint64 * add gguf key and tensor names for optimizer and training * add layer_norm_rms_eps to checkpoint convert script * use same GGUF_GET_KEY macro as in llama.cpp * use norm_rms_eps, and rope parameters and command line options to set them * fix memory corruption bug in gguf ctx->kv and ctx->infos was reallocated using not-aligned realloc, but freed with aligned free. to fix this a GGML_ALIGNED_REALLOC was added, but there is no posix_memalign_realloc function. so on non-windows and non-mingw32 platforms we fall back to aligned malloc, followed by copying and freeing the old data. * add gguf example cmake file * bug fixes in tokenize_file * bug fixes in load_llama_model_gguf * bug fix: init model when no checkpoint was loaded * bug fix in read_tensor_by_name * bug fix in load_opt_context_gguf * avoid printing lots of spaced on the unusual case that loss gets nan * set name of tensors with empty name from what was read from gguf * remove trailing whitespace * print data checksums before saving and after loading to verify correctness * bug fixes for convert-train-checkpoint-to-gguf * temporarily add code to write old checkpoint files used to verify that old checkpoint files are correctly converted to gguf * bug fixes for convert-train-checkpoint-to-gguf.py loading checkpoints with opt_version=0 * remove code used to verify correctness of checkpoint file conversion * remove trailing whitespace * remove prediction related code use main for prediction, it is better optimized * update train-text-from-scratch README.md * fix non-windows GGML_ALIGNED_REALLOC * add missing blank line at end of file * remove GGML_ALIGNED_REALLOC and use normal malloc/realloc/free for gguf ctx->kv & ctx->infos * train : fix compile warnings --------- Co-authored-by: Georgi Gerganov <ggerganov@gmail.com>

// GGML Tensor Library
|
|
//
|
|
// This documentation is still a work in progress.
|
|
// If you wish some specific topics to be covered, feel free to drop a comment:
|
|
//
|
|
// https://github.com/ggerganov/whisper.cpp/issues/40
|
|
//
|
|
// ## Overview
|
|
//
|
|
// This library implements:
|
|
//
|
|
// - a set of tensor operations
|
|
// - automatic differentiation
|
|
// - basic optimization algorithms
|
|
//
|
|
// The aim of this library is to provide a minimalistic approach for various machine learning tasks. This includes,
|
|
// but is not limited to, the following:
|
|
//
|
|
// - linear regression
|
|
// - support vector machines
|
|
// - neural networks
|
|
//
|
|
// The library allows the user to define a certain function using the available tensor operations. This function
|
|
// definition is represented internally via a computation graph. Each tensor operation in the function definition
|
|
// corresponds to a node in the graph. Having the computation graph defined, the user can choose to compute the
|
|
// function's value and/or its gradient with respect to the input variables. Optionally, the function can be optimized
|
|
// using one of the available optimization algorithms.
|
|
//
|
|
// For example, here we define the function: f(x) = a*x^2 + b
|
|
//
|
|
// {
|
|
// struct ggml_init_params params = {
|
|
// .mem_size = 16*1024*1024,
|
|
// .mem_buffer = NULL,
|
|
// };
|
|
//
|
|
// // memory allocation happens here
|
|
// struct ggml_context * ctx = ggml_init(params);
|
|
//
|
|
// struct ggml_tensor * x = ggml_new_tensor_1d(ctx, GGML_TYPE_F32, 1);
|
|
//
|
|
// ggml_set_param(ctx, x); // x is an input variable
|
|
//
|
|
// struct ggml_tensor * a = ggml_new_tensor_1d(ctx, GGML_TYPE_F32, 1);
|
|
// struct ggml_tensor * b = ggml_new_tensor_1d(ctx, GGML_TYPE_F32, 1);
|
|
// struct ggml_tensor * x2 = ggml_mul(ctx, x, x);
|
|
// struct ggml_tensor * f = ggml_add(ctx, ggml_mul(ctx, a, x2), b);
|
|
//
|
|
// ...
|
|
// }
|
|
//
|
|
// Notice that the function definition above does not involve any actual computation. The computation is performed only
|
|
// when the user explicitly requests it. For example, to compute the function's value at x = 2.0:
|
|
//
|
|
// {
|
|
// ...
|
|
//
|
|
// struct ggml_cgraph gf = ggml_build_forward(f);
|
|
//
|
|
// // set the input variable and parameter values
|
|
// ggml_set_f32(x, 2.0f);
|
|
// ggml_set_f32(a, 3.0f);
|
|
// ggml_set_f32(b, 4.0f);
|
|
//
|
|
// ggml_graph_compute_with_ctx(ctx, &gf, n_threads);
|
|
//
|
|
// printf("f = %f\n", ggml_get_f32_1d(f, 0));
|
|
//
|
|
// ...
|
|
// }
|
|
//
|
|
// The actual computation is performed in the ggml_graph_compute() function.
|
|
//
|
|
// The ggml_new_tensor_...() functions create new tensors. They are allocated in the memory buffer provided to the
|
|
// ggml_init() function. You have to be careful not to exceed the memory buffer size. Therefore, you have to know
|
|
// in advance how much memory you need for your computation. Alternatively, you can allocate a large enough memory
|
|
// and after defining the computation graph, call the ggml_used_mem() function to find out how much memory was
|
|
// actually needed.
|
|
//
|
|
// The ggml_set_param() function marks a tensor as an input variable. This is used by the automatic
|
|
// differentiation and optimization algorithms.
|
|
//
|
|
// The described approach allows to define the function graph once and then compute its forward or backward graphs
|
|
// multiple times. All computations will use the same memory buffer allocated in the ggml_init() function. This way
|
|
// the user can avoid the memory allocation overhead at runtime.
|
|
//
|
|
// The library supports multi-dimensional tensors - up to 4 dimensions. The FP16 and FP32 data types are first class
|
|
// citizens, but in theory the library can be extended to support FP8 and integer data types.
|
|
//
|
|
// Each tensor operation produces a new tensor. Initially the library was envisioned to support only the use of unary
|
|
// and binary operations. Most of the available operations fall into one of these two categories. With time, it became
|
|
// clear that the library needs to support more complex operations. The way to support these operations is not clear
|
|
// yet, but a few examples are demonstrated in the following operations:
|
|
//
|
|
// - ggml_permute()
|
|
// - ggml_conv_1d_1s()
|
|
// - ggml_conv_1d_2s()
|
|
//
|
|
// For each tensor operator, the library implements a forward and backward computation function. The forward function
|
|
// computes the output tensor value given the input tensor values. The backward function computes the adjoint of the
|
|
// input tensors given the adjoint of the output tensor. For a detailed explanation of what this means, take a
|
|
// calculus class, or watch the following video:
|
|
//
|
|
// What is Automatic Differentiation?
|
|

|
|
//
|
|
//
|
|
// ## Tensor data (struct ggml_tensor)
|
|
//
|
|
// The tensors are stored in memory via the ggml_tensor struct. The structure provides information about the size of
|
|
// the tensor, the data type, and the memory buffer where the tensor data is stored. Additionally, it contains
|
|
// pointers to the "source" tensors - i.e. the tensors that were used to compute the current tensor. For example:
|
|
//
|
|
// {
|
|
// struct ggml_tensor * c = ggml_add(ctx, a, b);
|
|
//
|
|
// assert(c->src[0] == a);
|
|
// assert(c->src[1] == b);
|
|
// }
|
|
//
|
|
// The multi-dimensional tensors are stored in row-major order. The ggml_tensor struct contains fields for the
|
|
// number of elements in each dimension ("ne") as well as the number of bytes ("nb", a.k.a. stride). This allows
|
|
// to store tensors that are not contiguous in memory, which is useful for operations such as transposition and
|
|
// permutation. All tensor operations have to take the stride into account and not assume that the tensor is
|
|
// contiguous in memory.
|
|
//
|
|
// The data of the tensor is accessed via the "data" pointer. For example:
|
|
//
|
|
// {
|
|
// const int nx = 2;
|
|
// const int ny = 3;
|
|
//
|
|
// struct ggml_tensor * a = ggml_new_tensor_2d(ctx, GGML_TYPE_F32, nx, ny);
|
|
//
|
|
// for (int y = 0; y < ny; y++) {
|
|
// for (int x = 0; x < nx; x++) {
|
|
// *(float *) ((char *) a->data + y*a->nb[1] + x*a->nb[0]) = x + y;
|
|
// }
|
|
// }
|
|
//
|
|
// ...
|
|
// }
|
|
//
|
|
// Alternatively, there are helper functions, such as ggml_get_f32_1d() and ggml_set_f32_1d() that can be used.
