Error in inference (libVSC)

Technical Support
#1

I’m facing this error while running inference. I’ve tried reinstalling the OS but to no effect

Traceback (most recent call last):
  File "resnet18.py", line 65, in <module>
    resnet18.nn_init(library=library, model=model, level=level)
  File "/home/khadas/.local/lib/python3.8/site-packages/ksnn/api.py", line 86, in nn_init
    val = self.ksnn_api.neural_network_create(library, model, level)
  File "/home/khadas/.local/lib/python3.8/site-packages/ksnn/kplatform/vim3/vim3_nn_api.py", line 9, in neural_network_create
    self.detect_so = CDLL(library)
  File "/usr/lib/python3.8/ctypes/__init__.py", line 373, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: libVSC.so: cannot open shared object file: No such file or directory
Ksnn changelog required
#2

I tried using this fix inside the ksnn directory and now I’m facing this error

@johndoe The least version is 1.2. So I ask you ,did you updat all repo to least ?

#4

Repo means ksnn or aml_npu_sdk?

Update: Updated ksnn to 1.2 and everything ran fine. Thanks @Frank for the help
