Installation on Windows with Python 3.9 fails

[BramVanroy]

Hello

I am trying to install spacy-udpipe on Windows with pip install spacy-udpipe on Python 3.9 but compilation fails. It does work on 3.7, however.

    Running setup.py install for ufal.udpipe ... error

Any idea?

[asajatovic]

Hello,

obviously this seems related to the UDPipe library, for which ufal.udpipe is just a Python binding. Please check out the requirements for installing UDPipe.

[BramVanroy]

Right, but that is exactly the issue that I try to make.

• the pip version does not have a pre-built wheel for Python 3.9
• the build process via pip fails

I know that you can simply follow the manual build instructions, but it would be great if pre-built wheels are available, or if building was possible from within the setup.py - but I am not sure whether that is possible.

[asajatovic]

In the Actions card, in the Install dependencies step of the pipeline Python package, you can clearly see that there isn't a pre-built wheel for any Python version from 3.6+ on Linux (example) for ufal.udpipe. Based on the provided stacktrace, I suspect that your issue is somehow related to the C++ compiler, but I can't be sure until I get my hands on a Windows machine (or a Docker image), and maybe not even then. In the meantime, I suggest you try submiting an issue to the UDPipe repository and/or using Python 3.7 as you mentioned it works fine.

[BramVanroy]

@asajatovic Oops, my bad. I thought for a moment that I was in the udpipe repository. I'll ask there.
