RuntimeError: dimension specified as 0 but tensor has no dimensions (backward) about lm-lstm-crf

I also find the same error "dimension specified as 0 but tensor has no dimensions" using torch-0.3.0. The author used torch-0.2.0 as said in requirement. I guess this is the problem. I haven't try torch-0.2.0 yet.

Hi,
happy holiday :-)
It should be --word_dim 200 instead of --embedding_dim 200.
Best,
Lucas

oh, sorry i didn't notice that you are using train_w instead of train_wc. Actually, for train_w, i'm not quite sure what causes the problem. would look into it later (if i find some time).

Hi,
Thank you,

Happy holiday :-)

@saharghannay amd @jerryitp were you guys able to resolve the error?

no, not yet

Also got the same issue here. No idea what caused it.

But I did try installing a previous version of PyTorch(0.2.0.post3), the error was avoided.

On Pytorch 0.3.1.post2

With tensors works fine:

a = torch.FloatTensor()
b = torch.rand(2,3)
a=torch.cat([a.clone(),b])

With Variables ERROR:

a = torch.autograd.Variable(torch.FloatTensor(), requires_grad=True)
b = torch.autograd.Variable(torch.rand(2,3), requires_grad=True)
a=torch.cat([a.clone(),b])
