pyO3 and HDF5 on windows

[dwerner95]

Hey All,
Sorry to bother you again!
I am trying to use hdf5-rust for a project with pyO3.

While the program works fine on Linux, I am having some trouble on Windows.
Therefore I created a MWE which is basically the HDF5 - Pixel example inside a working pyO3 Python-module.
You can find the whole code here.
Note: I can run the Pixel example on windows without issues if i do not use pyO3.

Compiling the code works on both, windows and linux, however execution fails on windows with the following error:
pyo3_runtime.PanicException: Can not create file: Invalid file access property list id: 720575940379279375
The same error occurred in #18, however i do not see with this explanation why it should work without Python but fail with it. Maybe I am misinterpreting it.
Can someone help me with this?

Wonder does the readme pixel example work without pyo3 on windows in your setup?

Hey @aldanor,

for whatever reason the plain rust example did run without throwing out an error, however you are right it did not run. The error seemingly occurred due to the same fact as #18.
Changing the HDF5 version from 1.12.1 to 1.10.7 worked for me.
Thank you both again for this cooperation. you've been really helpful (Even thought the errors where completely on my side.)

@dwerner95 No worries - hope it all works now. Closing this issue for now then. (and #194 leaving open for now due to #194 (comment))

Hello @dwerner95, I am having the same issue. Downgrading to 1.10.7 did not solve it for me. Did you do something else to make it work ? Thanks !
