   Hi @j143,
   
   thanks for having a look at my PR! 
   
   Sorry, I realised I still had a very low number for the negative samples in the Jupyter notebook. That caused the network to learn that basically almost every label should be 1 and hence immediately reached nearly zero loss. 
   
   I corrected the issue in the most recent commit and in the Colab notebook 😊 Not sure, if that's the same for everyone though.
   
   Cheers,
   Patrick
