Error related to Transformers version when launching

[tokenwizard]

On first run, I am getting this error during startup, after everything has downloaded:
A matching Triton is not available, some optimizations will not be enabled.
Error caught was: No module named 'triton'

A mixture of fp16 and non-fp16 filenames will be loaded.

ImportError: When passing `variant='fp16'`, please make sure to upgrade your `transformers` version to at least 4.27.0.dev0

It seems to indicate that it wants transformers 4.27.0 installed when the installation includes version 4.25.1.

I installed version 4.27.0 but then get the following warning from pip:

Now when running I wget this additional package version warning:

After installing version 0.17.0 of accelerate, it is now proceeding further with the run and downloading more data/models. I will report back if it actually runs successfully. But it seems odd the required version of these packages would not be installed by default during the setup process. FYI I am running Arch Linux and using python 3.10 in a venv.

Ok, after manually installing those two version of the those packages I have it running now.
Unfortunately, during stage III generation, I am running out of memory with my 16GB card. Time, to see where I can optimize.
