@isidentical Any idea why this fails?

[andygrove]

Perhaps it is because there is no recent version of maturin available in testpypi?

Can take a look at it in a couple of hours, if no one is found by then 👀 But yes, I think the problem seems to be that pip can't find the build dependencies on testpypi.

@andygrove just as a note (I didn't test it yet), but it might be worth to give a shot at --extra-index-url flag which allows to install stuff from both regular PyPI (like maturin) and TestPyPI (datafusion==0.7.0, considering it is not on the real PyPI)

pip install --extra-index-url https://test.pypi.org/simple/  datafusion==0.7.0

Thanks @isidentical ... that fixed it, and I have included this in the instructions in #83

Pretty cool to hear, I'll try to verify the last release artifacts and go through the release notes. Thanks so much for pushing this release, I think it is going to be really helpful to have the newest version of datafusion available in Python bindings.
