RuntimeError: CUDA error: device-side assert triggered in multiplication process

Hi, I got a weird error when I ran my project. This is a brief view of my code:

def __init__(self):
    ...
    self.entity_embedding = nn.Embedding(self.entity_num, self.dim)
    self.relation_embedding = nn.Embedding(self.relation_num, self.dim)

def forward(self):
    r_and_t = self.entity_embedding(relation) * self.relation_embedding(tail)
    r_and_t = torch.unsqueeze(r_and_t, dim=1)
    r_and_t = r_and_t.expand(r_and_t.shape[0], self.entity_num, self.dim)
    embed_head = self.entity_embedding.weight.expand(r_and_t.shape[0], self.entity_num, self.dim)
    print(r_and_t.shape)
    print(embed_head.shape)
    print((embed_head * r_and_t).shape)  #should get the same shape as the two above

Both self.entity_embedding and self.relation_embedding are nn.Embedding.

Everything is fine until runing process gets to the line:

print((embed_head * r_and_t).shape)

where I got the following information:

torch.Size([512, 14951, 100])
torch.Size([512, 14951, 100])

RuntimeError: CUDA error: device-side assert triggered

It looks that embed_head * r_and_t triggers error, but obviously embed_head and r_and_t are the same shape. In some previous similar posts people said the reason is index out of bound. But I don’t know how could it happen in a multiplication process. I still have no idea how to debug.

Anything I should note? Or anyone can tell me where is the possible mistakes?

Could you run the code with CUDA_LAUNCH_BLOCKING=1 python scrit.py and post the stack trace here?
The current error message might point to a wrong line of code.
Also, could you post the arguments and shapes of all layers and tensors, so that we could reproduce this issue?

Thanks for your help. I added os.environ['CUDA_LAUNCH_BLOCKING'] = '1' in my code and ran it again. Errors occurred as following:

RuntimeError: CUDA error: device-side assert triggered

This time it seems like error triggerred in line:

r_and_t = self.entity_embedding(relation) * self.relation_embedding(tail)

This is possible for a index out of bound mistake. I’ll check this!

I made a super stupid mistake!

r_and_t = self.entity_embedding(relation) * self.relation_embedding(tail)

Obviously, I mistakenly used relation to look up entity_embedding. and I even didn’t notice it. After correction, I could run successfully finally!
Thanks for your help again!
