Error while running clustimage module when embedding='tsne' #1

Closed spicker22 closed 2 years ago

spicker22 commented 2 years ago

An error occurs while running this module, clustimage. The error refers to the 'embedding' setting when "embedding='tsne'". If I run the code while "embedding='none'", it works fine. The concern is that embedding is very practical for visual purposes and should be used. Any ideas why this error occurs and how to resolve it?

setting

cl = Clustimage(method='pca',
                embedding='tsne',
                grayscale=False,
                dim=(128,128),
                params_pca={'n_components':0.95},
                store_to_disk=True,
                verbose=50)

Thank you for reporting! I found the issue: learning_rate='auto' seems the problem. I simply removed the parameter. Update to the latest version:

pip install -U clustimage
