I wanted to get the gradients from the gradient tape so in tf version 1 I used something like -

grads = model.optimizer.get_gradients(model.total_loss, model.trainable_weights)
symb_inputs = (model._feed_inputs + model._feed_targets + model._feed_sample_weights)

Now for tf v2 I want to get gradients so I used -

grads = tf.GradientTape(model.total_loss, model.trainable_weights)
symb_inputs = (model.feed_inputs + model.feed_targets + model.feed_sample_weights)

It is not working, I got errors like feed_inputs or feed_targets are not there.

the question needs sufficient code for a [minimal reproducible example](https://stackoverflow.com/help/minimal-reproducible-example) – D.L Aug 08 '23 at 13:06
Hi @D.L I wanted to get gradients something like this - https://stackoverflow.com/questions/51140950/how-to-obtain-the-gradients-in-keras – Shashank Priyadarshi Aug 08 '23 at 13:12
Closing this as I solved this issue. – Shashank Priyadarshi Aug 08 '23 at 14:16
