This is probably due to a problem with compiling Fortran code, as it should be built with the rest of HoloPy through f2py.

When I tried to run holopy3.5 on Windows, a problem occurred as above. Could anyone help me to solve it?

ViolaClem commented 1 year ago

I had the same problem and searched for a long time. Finally, it worked with Python version 3.6.13.

This should be fixed in the develop branch, which now relies on python 3.9. If you install the environment listed in environment.yml, including the m2w64-toolchain package, you should be able to compile the scattering extensions under Windows.

vnmanoharan commented 7 months ago

We hope to have a conda package for Windows available after the release, so that you don't have to compile the scattering extensions yourself.
