cannot import name '_topology' from partially initialized module 'lenstools.extern' #17
Description
I successfully installed lenstools from source code but I got an error message when importing it:
----> 1 from . import _topology
3 try:
4 from . import _design
ImportError: cannot import name '_topology' from partially initialized module 'lenstools.extern' (most likely due to a circular import) (/bigdata/birdlab/yyang440/LensTools/lenstools/extern/init.py)
Does anyone encounter the same issue?
