Current behavior?

can't restore because file structure changed. the .index file starts with CB1/ML/biases.

Standalone code to reproduce the issue

restore = tf.train.import_meta_graph('./Train.meta')
restore.restore(self.sess, tf.train.latest_checkpoint('./'))

I am trying to get this old project running in the latest version of TensorFlow so I can start migrating it to v2. Before I replace each function I want to get it running the the v1 api

@singersbalm To use the existing graph saved with the older TensorFlow version in your current session with a newer version. However, some functionality might be limited or compatibility issues might arise. To do this, simply use the import_graph_def function with the producer_version argument explicitly set to the older version. We recommend you to use the latest TF version by referring to the migration . If you still have any concern on TF v1, please post the issue on TF Forum. Thank you!

[singersbalm]

there is no producer_version argument in import_graph_def. the import attribute is of type GraphDef and not a path
