Pytorch 1.0 running problem

[Simon-Ace]

Hello, when I try to run the project with code python -m pointnet2.train.train_sem_seg, I got the following error.

=====>

AttributeError: module 'pointnet2._ext' has no attribute 'furthest_point_sampling'

the main problem seems to be in the folder _ext doesn't have the function or file which name is furthest_point_sampling. How to solve this problem? thanks

[erikwijmans]

Did you run python setup.py install? The _ext folder in the source tree only contains the c++/cuda needed to build the _ext module.

[Simon-Ace]

Thanks for your reply. I have rebuilt my project with your suggestion but still have the same error. (I remember that I have run this command in my first try.)

When I run this command python setup.py install, I got some warnings:

Seems like my compiler is not compatible with your compiler. Is this probably the source of the problem?

[erikwijmans]

Besides the warning, the rest of it looks fine/is what I would expect, so I would take that warning fairly seriously.

I am currently using g++ 5.4.0 to compile things, so I know that works. I don't have any control over the compiler pytorch uses to compile things, so can you give that a try on your end?

[palanglois]

Hi @Simon-Ace , Maybe you do run python -m pointnet2.train.train_sem_seg from the Pointnet2_PyTorch directory. In this case there is a name conflict for pointnet2 (the python module you built and the directory in Pointnet2_PyTorch).

[SSSuperMac]

@Simon-Ace @erikwijmans I have met the same error. It seems visdom caused the problem. When I comment two lines below https://github.com/erikwijmans/Pointnet2_PyTorch/blob/0c293e8491c2db994795e7b315e4002f38d1d9a7/pointnet2/train/train_cls.py#L139-L140 and set viz = None, then it works well. However, if so we can not see the training visualization. Maybe something in visdomviz.py needs update.

[erikwijmans]

I’ll take a look. Which version of visdom are you using?

[SSSuperMac]

I’ll take a look. Which version of visdom are you using?

urllib3: 1.24.1 visdom: 0.1.8.6

[erikwijmans]

Hmmm. Those are the exact same versions I am using with no trouble. It is also very odd that initializing the visdom client has anything influence on the _ext module.

The PR that I landed in master earlier today changes the default logging to simple prints with train/val loss and accuracy after every epoch, so at least that will provide some level of logging if disabling visdom continues the be on the only fix for you.

[SSSuperMac]

Yeah, I had tried the master in pytorch 0.4.1, and the same error occurred. So it seems the problem probably is caused by my environment, not your codes. I will try to find out that. Thanks very much for your response!
