Pyzed error Jetson TX2

dominik · November 12, 2023, 2:36pm

I set up fresh JetPack 4.6.4 and installed ZED SDK for JetPack 4.6.X (L4T 32.7)4.0 (Jetson Nano, TX2/TX2 NX, CUDA 10.2).

When I run: python3 object_detection.py
I get:
Traceback (most recent call last): File "object_detection.py", line 21, in <module> import pyzed.sl as sl ModuleNotFoundError: No module named 'pyzed.sl'; 'pyzed' is not a package

And python3 -m pip show pyzed
I get

Hello,

Are you sure you are running these commands in the same python environment ? What if you run them one right after the other in the same terminal ?

dominik · November 16, 2023, 12:09pm

Yes, they were run one after another in the same terminal. Moreover this is the error when I run get_python_apy.py

This is strange. Are you using the latest SDK version (4.0.8) ?
What if you install this wheel ?
pyzed-4.0-cp36-cp36m-linux_aarch64.whl (3.1 MB)

dominik · November 16, 2023, 12:40pm

I’ve installed this SDK version (accordingly to the docs) → https://download.stereolabs.com/zedsdk/4.0/l4t32.7/jetsons

When I try install your suggested wheels, the error is very similar:

Hi,

Is it a possibility for you to use a higher python version ?

Otherwise, you can also try to build the wrapper from source with a trick:
Replace in setup.py line 31
from setuptools import setup, Extension
with
from distutils import setup, Extension

Not sure that will work, but distutils is the legacy tools that we were using until recently. If that does not work either, it’s probably your python installation that is broken.

Answer a “little” bit late but maybe it will help someone.

I managed to run python api on default python 3.6, simply by updating:

pip3 install --upgrade pip setuptools wheel

next, when I tried to run python3 tutorial< x >.py I get:
Illegal instruction (core dumped)
but, I fixed that with:

export OPENBLAS_CORETYPE=ARMV8
