Using "auto" for rope alpha removes ambiguity on how to explicitly
enable automatic rope calculation. The same behavior of None -> auto
calculate still exists, but can be overwritten if a model's tabby_config.yml
includes `rope_alpha`.

It's best to pass them down the config stack.
API/User config.yml -> model config.yml -> model config.json -> fallback.
Doing this allows for seamless flow and yielding control to each
member in the stack.

Like config.json in a model folder, providing a tabby_config.yml
will serve as a layer between user provided kwargs and the config.json
values.

Storing a pathlib type makes it easier to manipulate the model
directory path in the long run without constantly fetching it

Use the tensor parallel loader when the flag is enabled. The new loader
has its own autosplit implementation, so gpu_split_auto isn't valid
here.
Also make it easier to determine which cache type to use rather than
multiple if/else statements.

* added chat template for firefunctionv2
* pulling tool vars from template
* adding parsing for tool inputs/outputs
* passing tool data from endpoint to chat template, adding tool_start to the stop list
* loosened typing on the response tool call, leaning more on the user supplying a quality schema if they want a particular format
* non streaming generation prototype
* cleaning template
* Continued work with type, ingestion into template, and chat template for fire func
* Correction - streaming toolcall comes back as delta obj not inside chatcomprespchoice per chat_completion_chunk.py inside OAI lib.
* Ruff Formating
* Moved stop string and tool updates out of prompt creation func
Updated tool pydantic to match OAI
Support for streaming
Updated generate tool calls to use flag within chat_template and insert tool reminder
* Llama 3.1 chat templates
Updated fire func template
* renamed llama3.1 to chatml_with_headers..
* update name of template
* Support for calling a tool start token rather than the string.
Simplified tool_params
Warning when gen_settings are being overidden becuase user set temp to 0
Corrected schema and tools to correct types for function args. Str for some reason
* draft groq tool use model template
* changed headers to vars for readablity (but mostly because some models are weird about newlines after headers, so this is an easier way to change globally)
* Clean up comments and code in chat comp
* Post processed tool call to meet OAI spec rather than forcing model to write json in a string in the middle of the call.
* changes example back to args as json rather than string of json
* Standardize chat templates to each other
* cleaning/rewording
* stop elements can also be ints (tokens)
* Cleaning/formatting
* added special tokens for tools and tool_response as specified in description
* Cleaning
* removing aux templates - going to live in llm-promp-templates repo instead

Previously, when a SIGINT was emitted and a model load is running,
the API didn't shut down until the load finished due to waitng for
the lock. However, when shutting down, the lock doesn't matter since
the process is being killed anyway.

A user's prompt and response can be large in the console. Therefore,
always log the smaller payloads (ex. gen params + metrics) after
the large chunks.
However, it's recommended to keep prompt logging off anyways since
it'll result in console spam.

If a job causes the generator to error, tabby stops working until
a relaunch. It's better to try establishing a system of redundancy
and remake the generator in the event that it fails.
May replace this with an exit signal for a fatal error instead, but
not sure.

API keys are not allowed to view all the admin's models, templates,
draft models, loras, etc. Basically anything that can be viewed
on the filesystem outside of anything that's currently loaded is
not allowed to be returned unless an admin key is present.
This change helps preserve user privacy while not erroring out on
list endpoints that the OAI spec requires.

If flash attention is already turned off by exllamaV2 itself, don't
try creating a paged generator. Also condense all the redundant
logic into one if statement.
Also check arch_compat_overrides to see if flash attention should

* Model: Clean up paged attention checks
* Model: Move cache_size checks after paged attn checks
Cache size is only relevant in paged mode
* Model: Fix no_flash_attention
* Model: Remove no_flash_attention
Ability to use flash attention is auto-detected, so this flag is unneeded. Uninstall flash attention to disable it on supported hardware.
* Model: More extensive checks for paged attention
Previously, TabbyAPI only checked for whether the user's hardware supports flash attention before deciding whether to enabled paged mode.
This adds checks for whether no_flash_attention is set, whether flash-attn is installed, and whether the installed version supports paged attention.
* Tree: Format
* Tree: Lint
* Model: Check GPU architecture first
Check GPU arch prior to checking whether flash attention 2 is installed
Cache size must be a multiple of 256 to work properly in ExllamaV2.
Take the config value and set the cache size to one multiple above
the remainder of the cache size divided by 256.
This is because cache size can never be lower than max_seq_len.
If max_seq_len isn't a multiple of 256, this method will never
yield a number that's lower than max_seq_len since it's no longer
a source of truth.

Depending on the day of the week, Starlette can work with a CancelledError

The dynamic generator requires Flash attention 2.5.7 or higher to
be installed. This is only supported on Nvidia's 30 series and higher.
If a card is AMD or lower than the 30 series, switch to compatability
mode which functions the same way as the older generator, except
without parallel batching and any features that depend on it, such as
CFG.
