Error to import emg3d

Dear Dieter,

I installed emg3d by pip and after that I wanted to import it but I faced with this error:

That is very weird. If you do a which pip3 in the terminal, what is the result? Did you try to install it with conda install -c conda-forge emg3d?

[kashkoulimohammad]

Thanks for replying. No, I didn't. I will try and let you know.

What I see is that your pip3 install emg3d also installs numpy, scipy, etc. However, afterwards you use anaconda. I would expect that in your anaconda environment there would already be numpy and scipy (unless you installed via miniconda. So my suspicion is that your pip3 points to another environment than your python3. But there might be other possibilities too, of course.

Thanks . My problem solved by use conda.
