DASFEnMAPbox / scipy.special import error / DLL laod failed

[Benjamin Jakimow]

Some apps that use scipy, like DASFEnMAPbox, raises ImportError:DLL load failed

Traceback (most recent call last):
  File "C:\PROGRA~1\OSGeo4W\apps\Python37\lib\code.py", line 90, in runcode
    exec(code, self.locals)

ImportError: DLL load failed: Das angegebene Modul wurde nicht gefunden.

How to reproduce:

from qgis.core import Qgis
import scipy
# print versions
Qgis.version()
scipy.version.version

# does this cause an error?
import scipy.special

observed in:

QGIS Version	Scipy Version	Error?

Hi,

Since I unfortunately had a HDD crash, I was reinstalling QGIS from scratch. Installing 3.12., all enmapbox apps are working. With 3.14.15-Pi installation the following errors occur:

EnMAPBoxApplication error(s): DASFEnMAPbox:

Can you call import scipy on your QGIS Python shell?

The numba error relates to #405 an can be solved by installed QGIS + EnMAP-Box + numba in a conda environment. See https://enmap-box.readthedocs.io/en/latest/general/faq_trouble.html#faq for details

[Benjamin Jakimow]

Seems to be an OSGeo4W QGIS only bug. I created a ticked here:

https://github.com/qgis/QGIS/issues/38489

[Benjamin Jakimow]

Looks like the issue has already been solved by the QGIS developers

https://github.com/qgis/QGIS/issues/38372

[Matthias Wocher]

Is there a patch coming with the next qgis version?

[Benjamin Jakimow]

My hope is that this comes as backport fix within the next days.

[Benjamin Jakimow]

The OSGeo4W installer allows to downgrade to 3.14.1, which solved the problems in my case.

[Benjamin Jakimow]

will be solved with QGIS 3.16
