Library sompy for implementing self-organizing maps

Question

I have installed the library sompy, but when I import it I have the next error:

  import sompy
  
  ImportErrorTraceback (most recent call last)
  <ipython-input-86-97d518356b3c> in <module>
  ----> 1 import sompy

  /opt/conda/lib/python3.8/site-packages/sompy/__init__.py in <module>
  1 
  ----> 2 from sompy import SOM

  ImportError: cannot import name 'SOM' from partially initialized module 'sompy' (most likely due to a circular import) (/opt/conda/lib/python3.8/site-packages/sompy/__init__.py)

This problem is explained here. The solution is to install a newer version of sompy:

pip3 install git+https://github.com/compmonks/SOMPY.git

There are also other, more up-to-date packages for SOMs available, for example minisom and susi.

Thank you! The library minisom is only for small datasets, isn´t it? – student-data-scientist Jun 15 '21 at 22:13
SOMs are mostly for small to medium-sized datasets. The "mini" in minisom corresponds to the minimalistic implementation. – felice Jun 16 '21 at 07:08
So if I have between 50.000 to 80.000 dates I need to use susi? – student-data-scientist Jun 16 '21 at 10:58
Should be fine for both. Just try them – felice Jun 16 '21 at 13:19
