"file too short" error when importing cv2 in container. Jetpack 5.1 and l4t-ml:r35.2.1-py3

[camilo2]

Hello. I flashed my AGX Orin with Jetpack 5.1 rev 1 and DeepStream 6.2 (and all the Runtime and SDK components). And without updating or upgrading anything, I pulled the docker image l4t-ml:r35.2.1-py3.

Then, inside the container, I get this error when I try to import cv2 in python3:

>>> import cv2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.8/dist-packages/cv2/__init__.py", line 96, in <module>
    bootstrap()
  File "/usr/local/lib/python3.8/dist-packages/cv2/__init__.py", line 86, in bootstrap
    import cv2
ImportError: /lib/aarch64-linux-gnu/libgstreamer-1.0.so.0: file too short

Hi @camilo2, did you start the container with --runtime nvidia? libgstreamer.so is one of the files that still gets mounted from the host device in /etc/nvidia-container-runtime/host-files-for-container.d/l4t.csv when the nvidia runtime is used. I just double-checked this container and was able to import cv2 okay.

Yes!, it was effectively the problem. Thanks!
