* SimpleChat: Add a skeletal html page
Contains a div placeholder for showing chat messages till now
a text-input for allowing user to enter next chat message/query
to the model.
a submit button to allow sending of the user entered message and
chat till now to the model.
* SimpleChat: A js skeleton with SimpleChat class
Allows maintaining an array of chat message.
Allows adding chat message (from any of the roles be it system,
user, assistant, ...)
Allows showing chat messages till now, in a given div element.
* SimpleChat: request_json, globals, startme
* SimpleChatJS: Roles Class, submitClick
Define Role class with static members corresponding to the roles.
Update startme to
* Get hold of the ui elements.
* Attach a click handler to submit button, which adds the user input
to xchats array and shows the chat messages till now in chat div
element.
Trap DOMContentLoaded to trigger startme
* SimpleChat:HTML: Bring in the js file
* SimpleChat: Rather value wrt input text element
* SimpleChat: Also add completions related prompt
* SimpleChat: Use common helper logic wrt json data
* SimpleChat: Move handling of submit request into its own func
* SimpleChat: Try handshake with llm over its web service endpoint
* SimpleChat:JS: Extract model response and show to user
* SimpleChat:JS: Messages/Prompt, indicate working to end user
* SimpleChat: Try keep input element in view
* SimpleChat: Diff user/assistant msgs, Make input wider
Also show a default message to user
Also add some metas
* SimpleChat: Move into its own sub directory to avoid confusion
* SimpleChat:sh: Add simple shell script to run python3 http.server
So one needs to run the llm server locally
then run this script and access it using a local browser
* SimpleChat:JS: Try trap enter key press wrt input text field
So user can either press submit button or press enter key
* SimpleChat: Allow user to select chat or completion mode
* SimpleChat: Dont submit if already submitted and waiting
Also make chat the default selection wrt mode
* SimpleChat:JS: Handle difference in response
Try read the assistance response from appropriate field in the
response got.
Also examples/server seems to return the response in a slightly
different field, so try account for that also.
* SimpleChat:JS: Force completion mode be single message by default
* SimpleChat: Add a simple readme file
* SimpleChat:HTML: Cleanup/structure UI a bit, Add input for system
* SimpleChat:Allow system prompt to be set, if provided before user
* SimpleChat: Ignore empty user input, without trimming
* SimpleChat:Alert user if they provide sysprompt late or change it
* SimpleChat: Move handling systemprompt into its own func
* SimpleChat:HTML: Add a style for system role message
* SimpleChat: Update the readme file
* SimpleChat:CSS: Move style info into its own css file
To keep it simple, clean and seperate so that things are not
unnecessarily cluttered.
* SimpleChat:CSS: Allow for chat div to be scrollable
* SimpleChat:JS: Try ensure the last entry in chat is visible
Needed because now only the chat div is scrollable and not the full
page.
In last commit the chat div size was fixed to 75% vertical height,
so the full page no longer scrolls, so the old bring user-input
element to view wont work, instead now the last element in the
chat div should be brought into view.
* SimpleChat:JS: bottom of element visible, Set focus to user input
As the generated text could be multiple lines and occupy more space
that the full scrollable div's vertical space, make the bottom of
the last element (which can be such a generated text) in the div
visible by scrolling.
Ensure that the user input box has focus
* SimpleChat: Update notes a bit. Try keep browser happy
Avoid browser quirk mode with DOCTYPE.
Help with accessibility a bit by specifying the language explicitly.
Specify the char encoding explicitly, inturn utf-8 is a safe bet,
even with intermixing of languages if reqd in future.
Add a cache-control http-equiv meta tag, which in all probability
will be ignored.
Defer js loading and execution, just for fun and future, not that
critical here as it stands now.
* SimpleChat:HTML:Group user input+btn together; Note about multichat
* SimpleChat:JS: Allow for changing system prompt anytime for future
* SimpleChat:Readme: Note about handle_systemprompt begin/anytime
* SimpleChat:HTML: Add viewport meta for better mobile friendliness
Without this the page content may look too small.
* SimpleChat:HtmlCss: Cleanup UI flow
set margin wrt vmin rather than vw or vh so portrait/landscape ok.
Use flex and flex-grow to put things on the same line as well as
distribute available space as needed. Given two main elements/line
so it remains simple.
In each line have one element with grows and one sits with a basic
comfortably fixed size.
* SimpleChat: textarea for multiline user chat, inturn shift+enter 4 enter
* SimpleChat: Make vertical layout better responsive (flex based)
Also needed to make things cleaner and properly usable whether
landscape or portrait, after changing to multiline textarea rather
than single line user input.
Avoid hardcoding the chat-till-now display area height, instead
make it a flex-growable within a flex column of ui elements within
a fixed vertical area.
* SimpleChat: Rename simplechat.html to index.html, update readme
Instead of providing a seperate shell script, update the readme wrt
how to run/use this web front end.
* SimpleChat: Screen fixed view and scrolling, Printing full
* SimpleChat:JS:CI: Avoid space at end of jsdoc param line
* SimpleChat:JS: MultiChat initial skeleton
Will help maintain multiple independent chats in future
* SimpleChat:JS: Move system prompt begin/anytime into SimpleChat
* SimpleChat:JS:Keep MultiChatUI simple for now
Worry about different chats with different servers for later.
* SimpleChat:JS: Move handle submit into MultiChat, build on same
Create an instance of MultiChatUI and inturn a instance of chat
session, which is what the UI will inturn work on.
* SimpleChat:JS: Move to dictionary of SimpleChat, instead of array
* SimpleChat: Move ui elements into MultiChatUI, Update el IDs
Move ui elements into MultiChatUI, so that current handleUserSubmit
doesnt need to take the element arguments. Also in future, when
user is allowed to switch between different chat sessions, the
UI can be updated as needed by using the elements in UI already
known to MultiChatUI instance.
Rename the element ids' so that they follow a common convention,
as well as one can identify what the element represents in a more
consistant manner.
* SimpleChat:MCUI:Show available chat sessions, try switch btw them
Previous commits brought in / consolidated existing logic into
MultiChatUI class.
Now start adding logic towards multichat support
* show buttons indicating available chat sessions
* on sessin button click, try switch to that session
* SimpleChat:MCUI: Store and use current chat session id
Also
allow to switch chat session optionally, wrt some of the related
helpers.
setup for two chat sessions by default.
* SimpleChat:MCUI: Delay enabling user-input to avoid race
Re-enable user-input, only after response to a user query has been
updated to the chat-div. This ensures that if user tries to switch
chat session, it wont be allowed till chat-request-response flow is
done.
* SimpleChat: Take care of system prompt
Helper to get the latest system prompt and inturn use same to
set the system prompt ui, when switching.
Ensure that system prompt is set if and when enter key is pressed.
* SimpleChat:GetSystemLatest, fix a oversight.
* SimpleChat:MCUI: Allow selected chat-session btn to be highlighted
Also have a general helper for setting class of children.
* SimpleChat:Cleanup corners
Show system prompt in chat space, when it is set by pressing enter,
as a feedback to user.
Alert user, if they try to switch chat session in the middle of
waiting for a response from the ai model.
* SimpleChat:MCUI: Ensure req-resp failure doesnt lock up things
* SimpleChat:MCUI: Support for new chat sessions
Also a general create button helper.
* SimpleChat:MCUI: CreateSessionBtn helper, use wrt NewChat
Also fix a oversight wrt using stale data wrt the list of chat
sessions.
* SimpleChat:MCUI: NewChat btn first before existing chat sessions
* SimpleChat:MCUI:CornerCases:Skip new chat, show only if current
Skip NewChat if user cancels or if one waiting for response from
the ai model.
Dont show a chat with newly got ai model response, if current chat
session has changed, some how. Chat session shouldnt be allowed to
change, if there is a pending response, but still as a additional
sanity check.
* SimpleChat: Update readme, title, show usage if no chat to show
* SimpleChat: Cleanup the log/dialog messages a bit
* Update brute force test: add_special
* Update brute force test: default values for add_bos_token and add_eos_token
* Enable rtrim when pre-inserting BOS

* server : fix test regexes
- Change '--embedding' to '--embeddings' in the README
- Update the description to match the latest --help output
- Added a caution about defining physical batch size
* [server] Cleanup a memory leak on exit
There are a couple memory leaks on exit of the server. This hides others.
After cleaning this up, you can see leaks on slots. But that is another
patch to be sent after this.
* make tab into spaces
* convert-hf : begin refactoring write_tensor
* convert : upgrade to sentencepiece v0.2.0
* convert-hf : remove unused n_dims in extra_*_tensors
* convert-hf : simplify MoE weights stacking
* convert-hf : flake8 linter doesn't like semicolons
* convert-hf : allow unusual model part names
For example, loading `model-00001-of-00001.safetensors` now works.
* convert-hf : fix stacking MoE expert tensors
`torch.stack` and `torch.cat` don't do the same thing.
* convert-hf : fix Mamba conversion
Tested to work even with a SentencePiece-based tokenizer.
* convert : use a string for the SentencePiece tokenizer path
* convert-hf : display tensor shape
* convert-hf : convert norms to f32 by default
* convert-hf : sort model part names
`os.listdir` is said to list files in arbitrary order.
Sorting the file names should let "model-00009-of-00042.safetensors"
be loaded before "model-00010-of-00042.safetensors".
* convert-hf : use an ABC for Model again
It seems Protocol can't be used as a statically type-checked ABC,
because its subclasses also can't be instantiated. (why did it seem to work?)
At least there's still a way to throw an error when forgetting to define
the `model_arch` property of any registered Model subclasses.
* convert-hf : use a plain class for Model, and forbid direct instantiation
There are no abstract methods used anyway,
so using ABC isn't really necessary.
* convert-hf : more consistent formatting of cmdline args
* convert-hf : align the message logged for converted tensors
* convert-hf : fix Refact conversion
* convert-hf : save memory with lazy evaluation
* convert-hf : flake8 doesn't like lowercase L as a variable name
* convert-hf : remove einops requirement for InternLM2
* convert-hf : faster model parts loading
Instead of pre-loading them all into a dict, iterate on the tensors
in the model parts progressively as needed in Model.write_tensors
Conversion for some architectures relies on checking for the presence
of specific tensor names, so for multi-part models, the weight map is read
from the relevant json file to quickly get these names up-front.
* convert-hf : minor changes for consistency
* gguf-py : add tqdm as a dependency
It's small, and used for a progress bar
in GGUFWriter.write_tensors_to_file
* Added themes support with two sample themes and a favicon.
* Newline
* Newline
* Newline
* Trailing whitespace
* Increased opacity for contrast
* Increase opacity.
Check actions cancelled for some other priority job and I can't seem to manually re-run them, so MOAR OPACITY
* Opacity action trigger.
Trying to re-trigger the cancelled action.
* One more opacity adjustment
