ModuleNotFoundError: No module named 'kaolin.nnsearch'

[Shabayek]

I'm using pytorch:19.10-py3 docker image (docker pull nvcr.io/nvidia/pytorch:19.10-py3). I get the following error:

Same error. I installed pytorch using conda on ubuntu 18.04 as per the instructions.

[shersoni610]

I had the same issue but it seems to get resolved if I run the code outside the directory i.e. above
README,md folder.

@shersoni610 : I tried the same in both 1) the docker image and 2) a conda environment, but I get the following error:
In the docker image:

For sure the cuda runtime exists as I'm working inside the docker image. Running nvcc --version:

I had the same issue but it seems to get resolved if I run the code outside the directory i.e. above
README,md folder.

I'm getting the same and this also fixes it for me.

[Kuldaen]

Actually it seems to work as long as it is in any folder besides the root of the git repository. ie I can go into examples and it is fine

[Shabayek]

@Kuldaen : I tried again from another folder beside the root of kaolin but I still get the same error:

[Kuldaen]

Sorry but cythonize error is something different from the nnsearch problem. You should create a new issue.

[Shabayek]

It is a follow up which happens when I start the installation from the parent directory of kaolin or another directory in the same level of kaolin. Otherwise, there is the no module named 'kaolin.nnsearch' error. Please recall that the instructions are to install from the kaolin directory. I created issue #60 for the new error.

[Kuldaen]

you can't run the installation from outside or in another directory. it has to be in the root of the git repository. you only have to run this once per virtual enviroment.

the nnsearch problem is separate, once you have installed it properly from there, you only need to run any python scripts that use kaolin from another directory.

[Shabayek]

If I run the code from outside the directory I get the following error:

[Kuldaen]

it should be print(kal.__version__)

[Shabayek]

This is what I'm doing but the underscores are automatically removed by the editor!!

Follows another example:
(kaoline) [user@access1 ~]$ python kaolin/examples/Classification/pointcloud_classification.py
Traceback (most recent call last):

Hi, thank you for using Kaolin! The library went through a major rewrite with the version 0.9.0, and only the core library components we can thoroughly test and maintain are now part of this repository. Please refer to our latest documentation:
https://kaolin.readthedocs.io/en/latest/

Closing the bug as it is no longer relevant to this repo.
