Error when trying to import memsurfer

[MSiggel]

Hi, I seemingly successfully installed memsurfer without issues. However, when I try to import the library

import memsurfer 

I get the following error:

Traceback (most recent call last):
  File "/home/tb/masiggel/anaconda2/envs/python3/lib/python3.8/site-packages/memsurfer-1.0.0-py3.8-linux-x86_64.egg/memsurfer/pymemsurfer.py", line 14, in swig_import_helper
    return importlib.import_module(mname)

During handling of the above exception, another exception occurred:

Hi. It seems your python configuration is inconsistent. Memsurfer is trying to use python3.8, but the vtk libs that you built are using python2.7.

what does your python default to?

I mistakenly ran the install_deps.sh outside of the correct conda environment. running within the right conda environment fixed this issue.

Thanks a lot for your help and looking forward to testing your tool now!
