Jetpack 5.0.2 libnvToolsExt.so missing for pytorch

Hello,

I installed Jetpack 5.0.2 Runtime and the Jetson SDK Components with the SDK Manager. Afterwards I followed the guide to install pytorch. When I import pytorch i get the following error:

nvidia@linux:~$ python3
Python 3.8.10 (default, May 26 2023, 14:05:08)
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import torch
Traceback (most recent call last):

    self._handle = _dlopen(self._name, mode)
OSError: libnvToolsExt.so.1: cannot open shared object file: No such file or directory

Note that I got an error while installing pytorch with pip:

WARNING: The scripts pip, pip3, pip3.10 and pip3.8 are installed in '/home/nvidia/.local/bin' which is not on PATH.

ERROR: Invalid requirement:  'LD_LIBRARY_PATH=/usr/lib/llvm-8/lib:/usr/local/cuda-11.4/lib64:'
Hint: It looks like a path. File 'LD_LIBRARY_PATH=/usr/lib/llvm-8/lib:/usr/local/cuda-11.4/lib64:' does not exist.

When using ls -la /usr/local/cuda-11.4/lib64/I get the following libraries:

The libnvToolExt.so is missing. Should that not be installed with the SDK Components?

Hi,

PyTorch and JetPack have some dependencies.
If JetPack 5.0.2 is used, please install the package listed in the below link:
https://developer.download.nvidia.com/compute/redist/jp/v502/pytorch/

Thanks.

The solution was to NOT install Jetpack 5.0.2 Runtime but the regular version.

That means that the claims here that the runtime version only does not include samples and documentation is wrong.

Hi,

Could you share more info about this issue?
The runtime package doesn’t include the header/sample/document.

Thanks.

Hi,

I first installed Jetpack 5.0.2 Runtime (rev 2) with the SDK Manager. As you can see in my first post there where less .so files in /usr/local/cuda-11.4/lib64/. When installing the regular Jetpack 5.0.2 there are more .so files and the required libnvToolsExt.so included (see my second post). I installed pytorch 1.13.0 following the guide as shown in the first post. Maybe a package is missing in the Runtime version that includes the libnvToolsExt.so?

Hi,

The runtime package only contains the essential library.
Thanks.
