Is this using the wheel from PyPI or did you build from source?

[qzx-120]

i used the wheel from PyPI and it gave me that error.

i reinstalled it using a wheel from here: https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyhdf
and it's working fine now.

So i guess it's the wheel in PyPI that has the error.
