I've tried to install different versions of torch and torchvision (0.10.0-0.14.1) with no luck.

Installed kaolin by:

% python3.9 -m pip install kaolin==0.12.0 --use-deprecated=html5lib -f https://nvidia-kaolin.s3.us-east-2.amazonaws.com/torch-1.12.1_cu113.html

Hi @kenorb , usually this kind of error happens when the torch version (including the cuda version) is not matching with the wheels you are selecting, can you verify that your torch version is 1.12.1+cu113 ?

I have a similar issue:
ImportError: /home/ubuntu/miniconda3/envs/kaolin/lib/python3.7/site-packages/kaolin/_C.so: undefined symbol: _ZNK3c1010TensorImpl36is_contiguous_nondefault_policy_implENS_12MemoryFormatE

I have cuda 11.6 and torch 1.12.1 installed, so I use
pip install kaolin==0.11.0 -f https://nvidia-kaolin.s3.us-east-2.amazonaws.com/torch-1.12.1_cu116.html but no avail.

Hi @samiede , please open a new issue, I'll try to help you. Again usually this kind of errors happen when there is a difference in torch version and kaolin's torch version (including cuda)

[wangsen1312]

similar problem here, any update on this?

[Caenorst]

Hi @wangsen1312 what is your error message, what is your torch version, what it your cuda version, what is your command-line?

[wangsen1312]

error message:
ImportError: /home/senw/anaconda3/envs/texture/lib/python3.9/site-packages/kaolin/_C.so: undefined symbol: _ZNK2at6Tensor8data_ptrIhEEPT_v

the pytorch version is 1.12.1 and cuda version is 11.3

I just check the kaolin version
python -c "import kaolin; print(kaolin.__version__)"

[Caenorst]

what was the command line to install kaolin?
also double check torch.__version__ and torch.version.cuda

[wangsen1312]

@Caenorst Thank you for your prompt response.
I install kaolin with pip install kaolin==0.11.0 -f https://nvidia-kaolin.s3.us-east-2.amazonaws.com/torch-1.12.1_cu11.3.html

I just double check the torch.__ version__ and torch.version.cuda. it is 1.12.1 and 11.3

[Caenorst]

There is a typo in your installation command-line it should be https://nvidia-kaolin.s3.us-east-2.amazonaws.com/torch-1.12.1_cu113.html

[wangsen1312]

There is a typo in your installation command-line it should be https://nvidia-kaolin.s3.us-east-2.amazonaws.com/torch-1.12.1_cu113.html

sorry for the typo. The error still exists

[Caenorst]

Actually looking at https://nvidia-kaolin.s3.us-east-2.amazonaws.com/torch-1.12.1_cu113.html there is no kaolin 0.11.0, do you need specifically 0.11.0 ? I suggest use the latest version

[wangsen1312]

@Caenorst Thank you for your support. it works now!
