Training model with the Poisson loss function and the Adam optimizer resulted in NaN loss about tensorflow HOT 3 OPEN

Hi @Calabashypr ,

• It looks like you are using an older Version of Tensorflow (2.0). Many bugs have been fixed in the latest version. Can you please execute your code using Latest Version (2.15.0 or 2.16.1) and let us know if the issue still persists?
  Thank you!

Hello,I have updated the Version of Tensorflow to 2.15.0,but I got an ERROR below:
[ERROR] Crash when training model with tensorflow Traceback (most recent call last): File "train.py", line 254, in <module> model, input_objects_names, output_layers_names, x, y, ins, ins_value = __prepare(flags.loss, flags.optimizer, File "train.py", line 69, in __prepare ins = model._feed_inputs + model._feed_targets + model._feed_sample_weights AttributeError: 'Functional' object has no attribute '_feed_targets'
Could you help me solve the problem?

Hi @Calabashypr ,
Apologies for the delay. The code provided is fairly complex hence it would be difficult for us to pinpoint the issue. Could you please get the example down to the simplest possible repro? or Could you please share the Colab gist with all dependencies?
Thank you!
