I have installed “iopath”,but still report same error，how can I solve it? I saw another issue saying that it was downgraded to Python 3 7. However, after I downgraded to python3.7, I was prompted that Python3.8 is required during installation. thanks

We don't officially support windows but uses have reported success with Python 3.8 in windows.

[KevinVCSFTWR]

Will windows be supported in the future?

[stephenroller]

The main barrier to us officially supporting windows is that no one has set up CI for windows. The entire development team works on Linux (and that will never change), so we need a representative environment.

We would welcome someone going through the steps of setting up CI and documenting installation procedures. From there, the team could easily identify and fix incompatibilities.
