Python Upgrade on Jetson Nano - Tutorial

[@viorelnegoita]

OpenCV works in Python3.6.9, how do I make it work in Python 3.8 and 3.11? Thanks

[@pablocarmona2485]

Hi i'm currently working on a project that uses python 3.11, but have to adapt it to jetson nano. We use someface detection models so I need the GPU, as far as I've seen there's no way to use gpu from another python different from the one that is built in with the jetpack. Please if you know a way to use the GPU from your other python installs it would be of much help!

[@JetsonHacks]

I don't think I understand enough about your issue to help give an answer. Usually Python is bound to the libraries that are using the GPU (PyTorch, Tensorflow, etc), not the GPU libraries themselves. You should ask for help in the official NVIDIA Jetson Nano forum. Thanks for watching!

How do I auto run a python script after reboot on Jetson Nano? I’ve added the absolute path of python3 followed by the absolute path of the .py file under the command section of the Startup Application window. However, the .py file doesn’t run after rebooting the Jetson Nano. How can I fix this issue?

[@JetsonHacks]

It's hard to tell without knowing how your script works. Here's a response video that may help: kzbin.info/www/bejne/e6mlqYiZn66pb8k Thanks for watching!

[@MWArduino]

great! but is cuda/torch working with python3.11? As it is installed in parallel, it does not look like a problem if not

[@JetsonHacks]

I would use the NVIDIA supported Docker images available on NGC for that kind of combination. There's lots of dependencies that need to be wrangled. Thanks for watching!

[@imadjawad4408]

Hi Jim, thanks for your time! I'm having a problem installing ServoKit, it give errors in the middle of the installation process, I updated pip3, and it started giving me user privileges errors, now I will try this installation, and then ServoKit, I read that the virtual environment may fix these root/admin issues, thanks again😀

[@viorelnegoita]

Great videos. Do you have one for installing a newer version of OpenCV?

[@MegaGippie]

hi man, thanks for the video. I tryed it by myself and faild with the build script... The instalation fails after 10 seconds with the same error that you got, but much earlier. The error: dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting dpkg-buildpackage: warning: (Use -d flag to override.) debuild: fatal error at line 1182: dpkg-buildpackage -us -uc -ui -i -I failed gbp:error: 'debuild -i -I -uc -us' failed: it exited with 29 I am trying to install python 3.11 on a Orin NX Dev kit 16GB. Currently running on Ubuntu 20.04 Can you help me out?

[@JetsonHacks]

I don't think those scripts would work on 20.04. They are for Ubuntu 18.04. You should follow the instructions on the dead snakes site for a currently supported platform: launchpad.net/~deadsnakes/+archive/ubuntu/ppa

[@MichaelSounhein]

Thanks! This is great and was something I was struggling with a bit with. I wonder if smaller LLM models can run on Jetson Orin Nano, as many require a newer Python version than what ships with it.

[@JetsonHacks]

You are welcome. It's a little bit easier to upgrade Python on the Orin Nano, as you can use the Deadsnakes PPA. This gives you access to the newer Python versions (as well as some of the older ones too). You don't have to build from source, like is done here. Thanks for watching!

Good morning! I built opencv with cuda support and it works now for python3.6 however i cannot import after installing python3.8 please tell me there is a way to use the same package without building everything from scratch

[@JetsonHacks]

It's difficult to say without knowing a lot more about how you run your Python setup. What did you do to install the new OpenCV on Python3.8?

[@bxoz3352]

@@JetsonHacks I installed opencv at first using your tutorial and it was on python3.6 the base version Now i need to use python3.8, i installed since it was already on the system (i followed this video). When i use python3 i can import cv2 and it works perfectly But when i use python3.8 i cannot import cv2

python3.11-full did not show up in my reposotiroy on jetson nano..

Last two weeks i was trying to do this even when i am getting to install p3.11 i am still having an error when installing cv2 with cuda. I hope also you tell us if there is a way to link python 3.11 with cv2 cuda. Thank you.

[@JetsonHacks]

I don't quite understand your question. Are you able to get Python 3.11 running? Did you build OpenCV with CUDA against Python 3.11. I don't know what the error messages might mean.

[@hssnov]

@@JetsonHacks I apologize when i am building the cv2 on python3.11 it will show everything ok but at the same time when i run Jtop i get cv2 not compiled with cuda. I will try your way and let you know. I am very thankful to you because i never used Jetson but after watching your vids i was able to implement image processing stuff for my university project. Thank you.

[@egbertprogrammer4408]

@@hssnov make sure opencv is replacing the one installed by jetson. There was a bug in opencv build, where it 'installs' but not registers. Not sure if this is the case with the current release.

[@gerardjulien2118]

Hi, Thanks for the video. Unfortunately it does not work in my case I have an Jetson Orin Nx, which is close to a Jetson Nano I replaced "git checkout ubuntu/bionic" by "git checkout ubuntu/focal" to match my ubuntu2004 in the script but it is not enough to do the trick --- Thanks in advance.

[@JetsonHacks]

The Jetson Nano does not support Focal, therefore there is no ubuntu/focal branch to check out. Perhaps you can go to a directly supported repository? launchpad.net/~deadsnakes/+archive/ubuntu/ppa Thanks for watching.

Hi Sir, i have two Jetson module...one is nano 2G and one is 4G. How to make a cluster so that I can use them for ML training.

This is more than can be explained in a YT comment. Please ask this question on the official NVIDIA Jetson Nano forum, where a large group of developers and NVIDIA engineers share their experience: forums.developer.nvidia.com/c/agx-autonomous-machines/jetson-embedded-systems/jetson-orin-nano/632 Thanks for watching!

Is it possible to install isaac-ros on jetson nano? any reference?

[@JetsonHacks]

I think it ran on pre-releases. I believe that the production versions are for JetPack 5 (Jetson Orin or Xavier). You can ask on the forum: forums.developer.nvidia.com/c/agx-autonomous-machines/isaac/isaac-ros/600

Absolutely incredible videos and it is really clear you know what you talking about and really understand the architecture. Any chance you can explain how you would install OpenCV with Cuda support now for Python 3.11? Your comprehensive guide on OpenCV with Cuda is incredible, but I am now completely lost because of the 2 different versions of Python 3 on the Jetson. I need to use Tensorflow so I installed Python3.11 and running in a virtual environment, but now I cannot get OpenCV installed because it is installed for 3.6. I don't mind building it again if that is what's needed - but not sure how to do it for python 3.11 as I cannot see in any of the build commands where to specify for which version it is.

[@JetsonHacks]

OpenCV has several optional flags you can use in the cmake definitions: -D PYTHON3_EXECUTABLE=$(which python3.x) \ # Replace 'python3.x' with your specific version -D PYTHON_INCLUDE_DIR=/path/to/python/include \ -D PYTHON_INCLUDE_DIR2=/path/to/python/include \ -D PYTHON_LIBRARY=/path/to/python/library \ -D PYTHON3_NUMPY_INCLUDE_DIRS=/path/to/numpy/headers \ That should get you closer to using 3.11.

I can use tkinter in 3.8.12, can you help me :(

[@JetsonHacks]

I don't what what you're asking. tkinter is part of Python.

[@nhatpham5797]

@@JetsonHacks I know, but jetson nano's Python is 3.6.9, when i use 3.6.9, i can import tkinter but if i use 3.8.12, i cant import tkinter

[@JetsonHacks]

@@nhatpham5797 First, check to see if tkinter is installed: python -m tkinter If not, you will need to install it. The installation will depend on how you intend to use it, for example if you're using a virtual environment or not. You should be able to find tutorials on the web to help you, that's not something I can help you with.

@@JetsonHacks The Jetank has not a flawless design. And the building video is challenging to follow. Lucky me i have a 3d printer to address some design flaws.
