Cant find training operation. Trying to use this to train a old keras model in C

[Eths33]

Trying to find the key graph operations, and I am not finding an easy way to find the training operation.

I added the following code to your python script from https://gist.github.com/asimshankar/7c9f8a9b04323e93bb217109da8c7ad2#file-train-c

In the code below train_op came right from the declaration of tensorflow operations. I am trying to find a way to get the training operation name from my keras model. Any ideas?

# tf.train.Saver.__init__ adds operations to the graph to save
    # and restore variables.
    saver_def = tf.train.Saver().as_saver_def()

    #print('Run this operation to initialize variables     : ', init.name)
    #print('Run this operation for a train step            : ', train_op.name)
    print('Feed this tensor to set the checkpoint filename: ', saver_def.filename_tensor_name)
    print('Run this operation to save a checkpoint        : ', saver_def.save_tensor_name)
    print('Run this operation to restore a checkpoint     : ', saver_def.restore_op_name)

    tf.train.write_graph(tf.get_default_graph(),  str(output_fld), 'graph.pb', as_text=False)

    # Readable but not correct for using with the example tensorflow C
    tf.train.write_graph(tf.get_default_graph(),  str(output_fld), 'graphText.pb', as_text=True)
