Broken Jetpack installation

I’m working with a Jetson Nano with 16GB of emmc storage, and I’m facing an issue in my Docker container based on l4t-pytorch:r32.6.1-pth1.9-py3

When trying to import torch inside of the container, the following error occurs:

>>> import torch
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/dist-packages/torch/__init__.py", line 196, in <module>
    _load_global_deps()
  File "/usr/local/lib/python3.6/dist-packages/torch/__init__.py", line 149, in _load_global_deps
    ctypes.CDLL(lib_path, mode=ctypes.RTLD_GLOBAL)
  File "/usr/lib/python3.6/ctypes/__init__.py", line 348, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: libcurand.so.10: cannot open shared object file: No such file or directory

My Jetson Nano is running Ubuntu 18.04. I also noticed that when I run jtop, it says “Jetpack UNKNOWN [L4T 32.5.2]” at the top

I’ve tried to install the nvidia-cuda and nvidia-jetpack metapackages, but they simply won’t fit in the Jetson’s 16GB disk

What can I do to allow Pytorch to work inside the container? Is there something that needs to be installed inside the container that might be missing?

Update: I switched to another Jetson Nano, and after pulling nvcr.io/nvidia/l4t-pytorch:r32.5.0-pth1.7-py3 and trying to run import torch inside Python 3 I got the exact same error.

A colleague suggested I’d add some more debug info:

$ uname -a

Hi,

libcurand is part of the CUDA library.
You will need to install the CUDA library to run the PyTorch.

If you are running out of the storage, please check if the below topic can help:

Thanks.

I was able to install the CUDA libraries that were missing on my Jetson and get PyTorch working

Thanks!
