Feature request: wheels for Python 3.8

[alimuldal]

It would be great to have pre-built wheels for Python 3.8 so that users of this version don't need to build dm-tree from source (and set up the requisite build dependencies, e.g. google-deepmind/dm_control#135)

Echo the request here.

This also affects Haiku; google-deepmind/dm-haiku#41

Hi together,

is there any update/solution of how to use dm-tree with Python 3.8 on Linux?

Try install Bazel

[alimuldal]

It looks as though wheels for Python 3.8 were added in June 2020: https://pypi.org/project/dm-tree/#files

[aiwalter]

@alimuldal so how to install this via wheels without error as above?

[alimuldal]

pip install dm-tree installs correctly from a wheel in a Python 3.8.9 virtualenv on an x64 Linux machine. I can't tell why pip is falling back on building from source in your case - it could be that you're using a non-standard python implementation, e.g. PyPy, or you might have unusual ABI requirements. The logs before Running setup.py install for dm-tree: started might contain more info. pip install --only-binary=all dm-tree might also give you a more useful error message. Either way, it's no longer the case that there aren't any 3.8 wheels available.
