Still the same problem:
In[122]:= NetMeasurements[net, testdata, "Accuracy"] Out[122]= $Failed
Hi Maha,
You need to run the trained net on test data to assess the accuracy and other metrics. Split your data into e.g. 80% train, 10% validation and 10% test. Use the train and validation data during training and then run NetMeasurements on the test data. Check the documentation for examples.
