Problems with running tutorials on Jetson Xavier (Ubuntu 18.04) #136

Closed GaneshArvapalli closed 4 years ago

GaneshArvapalli commented 4 years ago

Error: I've been having issues with both the Zed and the Zed 2 regarding an import error for pyzed.sl. The exact error for calling python3 tutorials/tutorial\ 1\ -\ hello\ ZED/hello_zed.py is as follows:

Traceback (most recent call last):
  File "tutorials/tutorial 1 - hello ZED/hello_zed.py", line 21, in <module>
    import pyzed.sl as sl
ImportError: libsl_core.so: cannot open shared object file: No such file or directory

Software Versions: I'm on ZED SDK 3.0.2 with CUDA 10.0. My Python version is 3.6.

Attempts at a solution: I've tried following the instructions from this link, but I'm still getting this error, even after rebuilding/installing using sudo python3 setup.py build/install and removing the SDK 2.8 install completely.

The output of ls /usr/local/lib/python3.6/dist-packages/pyzed* is

/usr/local/lib/python3.6/dist-packages/pyzed-3.0.egg-info

/usr/local/lib/python3.6/dist-packages/pyzed:
__init__.py  __pycache__  sl.cpython-36m-aarch64-linux-gnu.so

Thanks for the help!

It seems there's still a 2.8 version of pyzed installed somewhere, could you try this https://github.com/stereolabs/zed-python-api/issues/122#issuecomment-579348683 ?

Just in case you can remove (as in rm -rf) everything pyzed related, then reinstall the version compatible with the ZED SDK 3.0

This was the solution. Running sudo updatedb again revealed that there were instances of pyzed-2.8 that had not been removed after the first updatedb/rm -rf. Thank you!
