It seems there is something wrong with your input to the stn, you may print out the shape of the input in the point_net to see what happened.

from mmmot.

I have this error in same line of the code.
the input tensor size before linen x=x.view(-1, 1024 // self.reduction) is [1,1024].
and the error occurs at x=self.reslu(self.fc_bn1(self.fc1(x)))
How can I sove this problem?
my environment is pytorch 1.5.0, cuda10.2, and torchvision is 0.6.0 on python 3.7

from mmmot.

The code is used in Pytorch 1.1 and has not been used in 1.5. So the compatibility is not guaranteed.

from mmmot.

Thanks. After changing the Pytorch version to 1.1, the problem was solved.

该代码在Pytorch 1.1中使用，而在1.5中未使用。因此，不能保证兼容性。

thanks

Is this the environamnet that helped you fix the issue: pytorch 1.1.0, cuda10.2, and torchvision is 0.6.0 on python 3.7

@resplendent-star .could please give me the more details of the environment. I have a problem in pytorch and tried many times to solve but failed with the following errors:
vci-1@vci1:~/BR/fusion/mmMOT-master$ python eval_seq.py
段错误 (核心已转储)

from mmmot.

@resplendent-star this is my environment and have problem with the code .
