Problems with flowtron_libritts2p3k

[AI-Guru]

Hello!

I am very happy with Flowtron! I tested the flowtron_ljs model and it worked like a charm!

But when using the other two models, I run into problems. For example flowtron_libritts2p3k.

python inference.py -c config.json -f models/flowtron_libritts2p3k.pt -w models/waveglow_256channels_universal_v5.pt -t "I’ve seen things you people wouldn’t believe." -i 0

Gives me this output:

Traceback (most recent call last):
  File "inference.py", line 130, in <module>
    infer(args.flowtron_path, args.waveglow_path, args.output_dir, args.text,
  File "inference.py", line 53, in infer
    state_dict = torch.load(flowtron_path, map_location='cpu')['state_dict']
KeyError: 'state_dict'

Any ideas?

take a look at the keys for flowtron_libritts2p3k.
i think we saved the model instead of just the state dict.
the code below should solve your issue.

ck = torch.load(flowtron_path, map_location='cpu')
if 'model' in ck:
  state_dict = ck['model'].state_dict()
else:
    state_dict = ck['state_dict']

KeyError Traceback (most recent call last)
in
1 model_path = "models/model_10100"
----> 2 state_dict = torch.load(model_path, map_location='cpu')['state_dict']
3 model = Flowtron(**model_config)
4 model.load_state_dict(state_dict)
5 _ = model.eval().cuda()

KeyError: 'state_dict'

what do i do about this error?

and Please rafael or anyone who drop in to help, I am a newbee so please explain in easy way.

# load flowtron
    model = Flowtron(**model_config).cuda()
    checkpoint = torch.load(flowtron_path, map_location='cpu')
    if 'model' in checkpoint:
        state_dict = checkpoint['model'].state_dict()
    else:
        state_dict = checkpoint['state_dict']
    model.load_state_dict(state_dict)
    model.eval()
    model.cuda()
    print("Loaded checkpoint '{}')" .format(flowtron_path))

This should help!
