Tīmeklis2024. gada 10. maijs · First of all I would suggest you to use datagen.flow_from_directory to load the dataset. Also your model has become too simple now, try adding atleast 1or2 more Conv layers. Tīmeklis2024. gada 5. okt. · Here is the code that is output NaN from the output layer (As a debugging effort, I put second code much simpler far below that works. In brief, here the training layers flow goes like from the code below: inputA-> → (to concat layer) inputB->hidden1->hidden2-> (to concat layer) → concat → output

TīmeklisReLU has a range of [0, +Inf). So, when it comes an activation value z=0/1 produced by ReLU or softplus, the loss value computed by cross-entropy : loss = - (x*ln (z)+ (1 … Tīmeklis2016. gada 15. maijs · Regression with neural networks is hard to get working because the output is unbounded, so you are especially prone to the exploding gradients problem (the likely cause of the nans).. Historically, one key solution to exploding gradients was to reduce the learning rate, but with the advent of per-parameter adaptive learning …

TīmeklisLooking at the runtime log you probably won't notice anything unusual: loss is decreasing gradually, and all of a sudden a nan appears. What can you do: re-build your input datasets (lmdb/leveldn/hdf5...) make sure you do not have bad image files in your training/validation set.
Tīmeklis2024. gada 14. marts · nan values as outputs just mean that the training is instable which can have about every possible cause including all kinds of bugs in the code. If you think your code is correct you can try addressing the instability by lowering the learning rate or use gradient clipping.
