When starting the EnMAP-Box, I now get an error, because of the missing SIP package.

‌

[Benjamin Jakimow]

Please provide the error message

[Andreas Janz]

The bar is not showing anymore, but in the console I get:

Unable to import PyQt5-sip:
No module named 'PyQt5-sip'
D:\miniconda\envs\qgis\lib\importlib_bootstrap.py:219: RuntimeWarning: numpy.ndarray size changed, may indicate binary incompatibility. Expected 16 from C header, got 88 from PyObject

[Andreas Janz]

Is SIP not only for devs?

[Andreas Janz]

Like discussed, I removed the SIP from the requirements.txt

‌

[Andreas Janz]

Regarding the initial problem with setup_enmapbox_repository: this is only relevant for developers I guess.

I can’t reproduce the error on my Win10 system.

[Andreas Janz]

Benjamin, can’t you fix the problemeatic import in your QPS module?

[Andreas Janz]

This bug needs to be resolved locally by the user. We’ll adress it under the FAQ & Troubleshooting section:
