[POT] Error in Barycentre computation

Dear all I followed the 1D Wasserstein Barycentre demo on Github https://github.com/rflamary/POT/blob/master/notebooks/plot_barycenter_1D.ipy... and extended it to my use case where I have 100 pdfs/distributions with 5 bins each. I assign equal weights to each distribution and regularisation parameter value is same as the demo. So the dimensions of dataframes in my code are: A (5,100) M (5,5) weights (100) But on executing my code, I get the following error: C:\Users\Shikha\AppData\Roaming\Python\Python36\site-packages\ot\bregman.py:1049: RuntimeWarning: overflow encountered in true_divide u = (u.T * geometricBar(weights, UKv)).T / UKv Seeking help in resolving this error. Best, Shikha
