Adds a Nobreakmodel var that allows Breakmodel to be turned off. This can be done trough commandline or a model config (In case Neo is used by the models config without it being a true Neo model that is compatible with breakmodel).
In addition I removed the args.colab check for breakmodel support and instead make args.colab activate nobreakmodel. And I have added a new check so that breakmodel is not even attempted if you do not specify the layers but do launch a model from the command line.
Changed the model VRAM requirements to what you'd need to comfortably run the model rather than barely (Like with the manual). Will probably revise this in a later commit.
More importantly, it now supports models that use </s> which will be required to support XGLM and Fairseq models.
My last attempt at fixing this caused GPT2 to break, since the other fix is an edge case we assume that the GPT2 method should be used, and if that fails we try the other one to catch rare errors with bad model config's.
Turns out model_config does not work on models that have no model_type defined. In case this happens we now fall back to the old .json loading method. This will not work in --colab mode if its not already a local model, but since almost all modern models define a model type and to my knowledge all models on huggingface do that should not be an issue. If it is we can always ask the model creator to either update it, distribute the model differently or load that model with --remote instead of --colab.
In TPU instances, `vars.sp.shape[0]` is not always the actual number of
tokens in the soft prompt. We have to use `vars.sp_length` to get an
accurate token count.
Breakmodel is useless on Colab, so for the sake of efficiency if --colab is present we will always assume a model is incompatible. The same applies to the conversion, colab's are discarded so converting the model to a .bin file only wastes time since the HDD isn't fast. Finally we automatically set all the useful variables for Colab, so that in the future this can be removed from ckds and other scripts.
Lastly ckds has been adapted not to copy the examples folder and to add the new --colab parameter.
Local players are much better off running the old --remote command.
No longer update the chatname outside of the config, this will not effect singleplayer tab at all, but it will allow people in multiplayer to chat with their own names.
To prevent confusion with users who have not used KoboldAI for a while, or who are following old tutorials I have added a disclaimer that informs people that most Colab links should not be used with this feature and instead opened in the browser.
