I'm getting "nan" value for loss, while following a tutorial from the documentatin
Hi,I’m following the “Fine-tuning with Custom Dataset” tutorial for Question Answering on the SQuaD dataset tutorial:available here. I’ve copy pasted all the code shown in the tutorial step by step. However, when my model starts training, I don’t get the expected metric values for loss as I normally would, instead I get “nan”. Here is the output when I run themodel.fit(train_dataset.shuffle(1000).batch(16), epochs=3, batch_size=16)Epoch 1/35427/5427 [==============================] - 4604s 848ms/step - loss: nan - output_1_loss: nan - output_2_loss: nanEpoch 2/3365/5427 [=>…] - ETA: 1:11:28 - loss: nan - output_1_loss: nan - output_2_loss: nanI don’t know what is wrong, and I don’t think this output is what is supposed to be.Would appreciate any help with this regard.Thank you.
