Building wheel for tokenizers (pyproject.toml) did not run successfully - Python 3.9.9 - Windows 10

Yes there are several other questions like this but no solution provided

I am trying to install and run this project

https://github.com/xashru/punctuation-restoration

I have cloned the github repository

Installed rust from here downloading x64 : https://www.rust-lang.org/tools/install

I am using

Solution

As far as I can see it comes down to a version conflict. The versions of transformers and tokenizers are severly out of date.

On the rust side, that means that a rust feature (const_fn) tokenizers is using, is by now part of rust and not a nightly feature anymore (this is what the error output shows the compiler is complaining about).

In my eyes you have two main options:

updating the dependencies
install a very specific rust version

To update the dependencies manually change the requirements.txt and change the version numbers of transformers (and tokenizers). Ideally to the newest version. This might or might not work, depending on the repository, since they might depend HARD on that version of transformers / tokenizers. I would still try it out in your case, as this is the easy option.

Setting a sepecific rust version could be another way. You need to use a tool like rustup to install an older rust version that is compatible with the install. This means checking that specific version of tokenizers and see if they referred to the rust version or otherwise going by the commit timestamp to install the proper rust version of this time. This should work, but will of course use a lot of old libs and rust, so definitely not advised if you can get it to work otherwise.
