Error in GenTransConv + GenTransConv? #403

Open LifeBeyondExpectations opened 3 years ago

LifeBeyondExpectations commented 3 years ago

Describe the bug

When I attach the same network that is proposed in 'example.completion'

# declare network
net = CompletionNet(...)

# inference from 1st auto encoder
preds, ... = net(inputs)

# update input using the prediction from the previous network
updated_inputs = inputs + preds

# inference from 2nd auto encoder
updated_preds, ... = net(updated_inputs) # <- raise errors.

Meanwhile, if I change the generative transpose conv in the second network with the original transpose conv, the error did not happen. Moreover, sometimes, during the inference, it is okay. But still, it raises errors while computing backward gradients.

You can easily reproduce errors.

I am not sure this is my own problem. Thank you.

To Reproduce https://github.com/NVIDIA/MinkowskiEngine/blob/b71caef9b45ab32c02d2c1b5f48f13c1eb5df526/examples/completion.py#L611

...
out_cls, targets, sout = net(sin, target_key)

# ADD two lines
sin = sin + out_cls[-1]
out_cls, targets, sout = net(sin, target_key)

# origin code
num_layers, loss = len(out_cls), 0
...

Expected behavior I guess I can sequentially attach two auto-encoder networks that contains generative transpose convolution layers. But I got errors.

Let me print my error messages.
