Error: Not compiled with cuda

[sbharadwajj]

Hi,

so I pip install chamferdist, installed via pip. But when I run my training loop where both source and target is in cuda.(), I get the following error:

Traceback (most recent call last):
  File "train.py", line 114, in <module>
    loss_net = chamferDist(pred, gt, bidirectional=True)

This could be because you aren't using pytorch 1.6?

Compiling from source is the recommended way to install the package

[sbharadwajj]

I am using pytorch 1.6, cuda 10.1

But I will try compiling from source now. I am using a singularity environment thats why I used pip.

[krrish94]

Ah yes - could also be a cuda error. The pypi package was compiled with CUDA 9.0 iirc

[sbharadwajj]

okay, I dont have a torch 1.6 cuda 9 compatible docker. Will compiling from source work?

[krrish94]

should work :)

[sbharadwajj]

I am unable to build from source because I dont have root access. Is there anything I can change?

What are the specs for PyPi package? Cuda 9.0 and torch 1.6?

[krrish94]

As far as I know you wouldn't need root access to build from source. The recommended way is to use a conda / virtualenv environment

Hi Krishna,

I was revisiting this repo today and I remember facing a similar issue. I tried it with PyTorch 1.5, 1.6 and CUDA 10.1. I was building from source.

What version of PyTorch / Cuda do you have?

[krrish94]

I just reran CI on my end and I can confirm the following pytorch and CUDA versions work

pytorch 1.5, 1.6, 1.7
CUDA 9.2, 10.0, 10.1, 10.2

It would help to know more details about the error

[AkbarShah96]

Here is a screenshot of the error I get.

Edit: I also tried building from source on my Windows machine but couldn't get it to build. Attached log file.
pytorch: 1.6, CUDA 10.2 and pytorch 1.7, CUDA 11.0

[krrish94]

Can you try running example.py from this repo?

[AkbarShah96]

Similar error I guess.

[saryazdi]

@AkbarShah96 From the error log you posted for building from source, it seems like you're building from source with python setup.py build. Try uninstalling chamferdist and removing the build/ folder, then re-installing with pip install .. I remember getting some build errors on windows without pip in the past.

[AkbarShah96]

@saryazdi I tried your suggestion however I am getting another error. Seems like there might be some additional prerequisite steps to consider. Similar errors also occurred today when I tried to get the chamferdist from PyTorch3D on Windows.

[krrish94]

Interesting note, thanks. Question: Does the same error occur if you do python setup.py build develop ?
