@mgruben\r\n\r\nThe lab has 10 classes, so getting an accuracy of 0.1 is just the neural network randomly guessing which is the correct label.  This is either due to a bad model or bad training data.  Since the lab provides most of the model, it's probably bad training data.  Deleting the pickle file and rebuilding it should fix most problems with bad training data.\r\n\r\nBefore you delete the file, please send me a link to your pickle file so I can analyze it and prevent other student from making the same mistake."}}
