4 years ago @mdegans the version I installed was r32.4.2. Is there something else I should check?

Gotcha. That's JetPack 4.4. It's super confusing since the r32.xx versions do not align with the JetPack version.
I am running a test build now on an NX of the same release. I will let you know if I hit the same error.

4 years ago So, I can't replicate. Here are my steps to a working install. My starting point is a more or less unmodified, fully-updated JetPack 4.4.
To build and install, I did:
./build_opencv.sh 4.4.0My output from opencv_version --verbose is:

Did you build from master? Since I first suggested that, 4.4.0 has been tagged for release, so the above command should be used. I will change the default version so only build_opencv.sh is required.
For your issue, I would suggest that if OpenCV is important to you, it might be easier to backup, reflash, fully update, and then start the script again. Alternatively you can retry with an umodified script and build_opencv.sh 4.4.0 like above. Let me know if either of those solutions work for you @ben-mcdonnell-hacksmith or if you continue to have issues with the build.

4 years ago Okay, thanks! I figured the issue is with my system having an old version linked somewhere. I will try the 4.4 build tomorrow. maybe try to find the old version and unlink it. If all else fails I will rebuild the system.
Thanks, I will report back as soon I have figured it out.

4 years ago So I removed the old OpenCV entirely, I installed using your script and cv 4.4. Still have the same import error, but when I run help('modules') in python3 it seg faults, does that have anything to do with this?

@ben-mcdonnell-hacksmith
I suspect there may be another version of OpenCV installed in python path other than the one under the /usr/local prefix. Did you run pip3 install opencv-python at some point? That would put one under ~/.local/
Can you open a python3 interpreter and provide the results of this:
>>> import os
>>> import sys
>>> import itertools
>>> for p in sys.path:
... for root, dirs, files in os.walk(p):
... for name in itertools.chain(dirs, files):
... if name.startswith('cv2'):
... print(os.path.join(root, name))
...
/usr/lib/python3/dist-packages/cv2.cpython-38-x86_64-linux-gnu.so(you should see something slightly different)
If you see a file/dir in /home/your_user/.local/... try deleting it (or that python path in it's entirety). If one is in /usr you can remove it with sudo apt remove python3-opencv. The only one that should exist is under /usr/local as shown by opencv_version --verbose
If that still doesn't work, the only thing I can suggest is to backup, reflash, update, and retry build_opencv.sh. Note: the scrip's default version is now 4.4.0 so there's no need to add anything.

4 years ago This is what the output of that looks like `
import os import sys import itertools for p in sys.path: ... for root, dirs, files in os.walk(p): ... for name in itertools.chain(dirs, files): ... if name.startswith('cv2'): ... print(os.path.join(root, name)) ... /usr/local/lib/python3.6/dist-packages/cv2 /usr/local/lib/python3.6/dist-packages/cv2/python-3.6/cv2.cpython-36m-aarch64-linux-gnu.so `
Does that look right?

4 years ago That looks right, @ben-mcdonnell-hacksmith
Let's try something new.
sudo mv /usr/local/lib/python3.6/dist-packages/cv2 /tmp/cv2.bak
python3 -c "help('modules')"
sudo mv /tmp/cv2.bak /usr/local/lib/python3.6/dist-packages/cv2If help('modules') works after removing the cv2 built by the script, that's definately the issue, and not some other module that cv2 might import (I don't know if it does or not, TBH). If it still crashes, then the problem is somthing else.
Also, Now that you've rebuilt 4.4.0, can you provide the results of opencv_version --verbose again? I'd like to compare against my own build config.

@ben-mcdonnell-hacksmith If you moved cv2 out of the python path and it still crashes when you do help('modules'), then I think the problem is unrelated to cv2, rather something else that's being imported (numpy maybe?). We're narrowing it down at least, so progress :)
Can you cause a crash with import numpy or import scipy?
If one of those fails, then that would be the root cause. If that's the case, can you the same code as above, just for numpy or scipy instead of cv2 like:
>>> for p in sys.path:
... for root, dirs, files in os.walk(p):
... for name in itertools.chain(dirs, files):
... if name.startswith('numpy'):
... print(os.path.join(root, name))
...

4 years ago None of those throw errors. The cv error is probably related to an old version somewhere, but I can't find anything anywhere. I may try making a new image, but I do have a variety of other stuff installed and it would take a while to rebuild. And if this happens again I would like to figure out how to fix it.

Oh, I'm pretty sure it can be fixed by reflashing, updating, and running the script again, but like you, I'd like to know what's causing this.

(gdb) I have no idea how to interpret the output of this, but I think it could have something to do with the shared list library issue.

4 years ago Nevermind. I was thinking of another issue on a separate project with a core dump. Can you try a sudo ldconfig and see if you can import cv2 after that?. If that doesn't fix it, can you provide the output of:
ldd /usr/local/lib/python3.6/dist-packages/cv2/python-3.6/cv2.cpython-36m-aarch64-linux-gnu.so | grep cudnnThat should give you something like:
libcudnn.so.8 => /usr/lib/aarch64-linux-gnu/libcudnn.so.8 (0x0000007f5cc83000)I get an output from the ldconfig that appears to have some errors, but it doesn't fix the import issue:

From the other command I get the output: libcudnn.so.8 => /usr/lib/aarch64-linux-gnu/libcudnn.so.8 (0x0000007f88b43000)

Looks like there is somethign wrong with your cudnn install maybe?
Try:
sudo apt install nvidia-cudnn8 libcudnn8-dev --reinstallThat shuould perform a full reinstall of cudnn8. Cv2 may just start working after that. I'd imagine if you are getting the above errors, other things that use cuDNN will also crash in the same way.

4 years ago So that didn't fix it, but the error still appears when running ldconfig, is there a way to manually uninstall cudnn and reinstall it?

@ben-mcdonnell-hacksmith
That would be the manual way :(
At this point, I'm really not sure what's wrong. Although i'm pretty sure a reflash will fix it, as you say, I can't guarantee it won't happen again. One way to find out is maybe to build OpenCV first and keep applying your other changes, testing after each one to see what breaks cv2. If you can figure out what did it, that would be very helpful. I'll leave this issue open.

4 years ago @mdegans I made a new SD Card with a fresh install of JetPack, It did fix it as we figured. I still have the old card laying around in case I want to revisit it. But thanks for all your help!

Sorry we couldn't figure it out. Hopefully (?) somebody else has this issue and reopens this. I don't much like these kinds of mysteries :)
I am running an Xavier NX with Jetpack 4.2. After an OTA update cv2 won't import (before or after building with this script). To on my system I can build OpenCV running
