Hello,

I am using YOLOP for my application.
I am using Jetson Xavier for my application.
Since there is no docker file, I created a custom dockerfile. Please find dockerfile attached. Docker build was successful. But when i run below command inside container as mentioned in the readme instruction for testing an image, i get below error and i am not able to figure out what is the issue and what is the solution.

command executed:
python3 tools/demo.py --source images/inp --save-dir images/outp

Error Log:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/dist-packages/sklearn/__check_build/__init__.py", line 44, in <module>

It seems that scikit-learn has not been built correctly.

If you have installed scikit-learn from source, please do not forget
to build the package before using it: run `python setup.py install` or
`make` in the source directory.

If you have used an installer, please check that it is suited for your
Python version, your operating system and your platform.

Hi,

Since scikit-learn is pre-installed in the l4t-ml container.
Would you mind building the container with l4t-ml base instead?

Thanks.

Ok i Shall try l4t-ml:r32.5.0-py3 as base image rather than nvcr.io/nvidia/l4t-pytorch:r32.5.0-pth1.7-py3 .

I am converting requirements.txt to docker.
As per above requirements.txt i need to have opencv-python>=4.1.2, but l4t-ml:r32.5.0-py3 contains OpenCV 4.1.1. Would you suggest me to overwrite this again inside Dockerfile?

My worries is i should not miss any thing from requirements.txt for my application using yolo panoptic.

My nvdia jetpack details are as follows:

Package: nvidia-jetpack
Version: 4.5-b129

Hello, Another question is that I am going to build my application using ros2 foxy and hence i used nvcr.io/nvidia/l4t-pytorch:r32.5.0-pth1.7-py3 initially. I hope changing the base image will not create any problem. It is just my guess and i am trying to avoid any rework.

7

Hello, I am unable to pull the base image as suggested above.

Step 1/16 : FROM l4t-ml:r32.5.0-py3
pull access denied for l4t-ml, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
8

I am able to pull image with below command:
FROM nvcr.io/nvidia/l4t-ml:r32.5.0-py3

I will get back if it solves my original scikit-learn issue or not.

Hello,

I was able to use scikit-learn without any error with below base image.

FROM nvcr.io/nvidia/l4t-ml:r32.5.0-py3

Thanks for your support.

Regards,
Monalisa.
