sevamoo/SOMPY

As much as possible, the structure of SOM is similar to somtoolbox in Matlab. It has parallel processing option similar to sklearn format and it speeds up the training procedure, but it depends on the data size and mainly the size of the SOM grid.I couldn't manage the memory problem and therefore, I recommend single core processing at the moment. But nevertheless, the implementation of the algorith is carefully done for all those important matrix calculations, such as scipy sparse matrix and numexpr for calculation of Euclidean distance. Installation: Download and extract this repo. Copy the extracted folder to the'site-packages' folder of your Python installation. You can then import SOMPY.
