MacOS Monterey 12.2.1
I'm using current stable sklearn (1.1.1), Python 3.8.9. I hit the following errors:

File "/Users/rene/.venv/ahead2/lib/python3.8/site-packages/SOMperf-0.2b0-py3.8.egg/somperf/metrics/external.py", line 6, in
ModuleNotFoundError: No module named 'sklearn.metrics.cluster.supervised'

somperf/metrics/external.py, line 6: from sklearn.metrics.cluster.supervised import check_clusterings

I managed to find sklearn source here (0.17.1): https://gemfury.com/stream/python:scikit-learn/-/content/metrics/cluster/supervised.py; pasted the check_clusterings definition into external.py, reinstalled and then hit the following:

File "/Users/rene/.venv/ahead2/lib/python3.8/site-packages/SOMperf-0.2b0-py3.8.egg/somperf/metrics/external.py", line 7, in
ModuleNotFoundError: No module named 'sklearn.utils.linear_assignment_'

sklearn 0.17.1 won't build on my machine. 0.22.2 doesn't have these problems, but consistently segfaults.

Please add version numbers to requirements.txt (and maybe reply here with them, too).

Thank you.

Hi there,

I am trying to use BMU values a metric to classify my data. Features are seismic attributes.
Your function “distance_from_weights” was my first guess but it´s not exporting BMUS directly. We do have to manipulate it to remove the second BMU.

np.argsort(distance_from_weights(data), axis=1)[:, :2] -----> np.argsort(distance_from_weights(data), axis=1)[:, :1]

Do you mind to build that function?

Hello Mr. Florent

Could we think to do crossplots train/test x epochs? If so do you mind to show us an example?

Hello,
I have one problem and one question:

1)While loading the SOMperf libraries, I receive an error from the external methods: No module named 'sklearn.metrics.cluster.supervised'. Research online suggest this might occur because of a mix of pip and conda-versions of libraries, but I tried in another computer with only conda-installed libraries, and sadly the same problem occurs.

2. Is there a way to estimate the topographic product with SOMperf using SOMPY?

Thank you very much!

Olaf
