Error while running synthesizer_train.py

[narendranp]

Hi,

When I running python3 synthesizer_train.py vc_adversarial VC_basedir/SV2TTS/synthesizer_train/ , I getting the following error. By reading the error, I can understand that process stops at "expanded_g = tf.expand_dims(g, 0)" in tacotron.py. I am unable to understand how to overcome this error. Can you please help me solve the above issue.
