I am using neurokit2-0.0.39-py2.py3-none-any.whl file . After import neurokit2 as no it is giving following error. I have set Storage/Internet permission in Android Manifest. Can you please help us what permission require for 'Convert' or any other solution.

I can't reproduce this problem. Does it happen on all devices and emulators? If not, which ones does it happen on?

And have you attempted to provide the "convert" program yourself?

[mhsmith]

Actually sorry, I can reproduce it now, but only on a physical device, not an emulator.

I'll look into it and see if I can come up with a workaround.

[mhsmith]

I think it's caused by inaccessible directories on the PATH. Try running this code before you import neurokit2 or matplotlib:

import os
os.environ["PATH"] = ":".join([p for p in os.environ["PATH"].split(":")
                               if os.access(p, os.R_OK | os.X_OK)])

It worked for me, Thank you !

This issue is fixed in Chaquopy 9.0.0. To upgrade, edit your app's top-level build.gradle file and change the version number of com.chaquo.python:gradle.
