ValueError: could not load library libvx_tidl_rt.so #16

Hi,

I have compiled the dockerfile and run the setup.py. it seems everything goes well, and i get these libraries in ./tidl_tools dir: PC_dsp_test_dl_algo.out libonnxruntime.so libtidl_onnxrt_EP.so libvx_tidl_rt.so.1.0 tidl_graphVisualiser_runtimes.out tidl_model_import_tflite.so device_config.cfg libonnxruntime.so.1.7.0 libtidl_tfl_delegate.so ti_cnnperfsim.out tidl_model_import_onnx.so itidl_rt.h libtensorflow-lite.a libvx_tidl_rt.so tidl_graphVisualiser.out tidl_model_import_relay.so

however, when i try to run ./scripts/run_python_examples.sh, an error was thrown as follows:

is there anything i can do to fix this problem? thanks for your reply in advance.

Some additional information that may be useful

at the first time i run ./scripts/run_python_examples.sh, i got the following error: Traceback (most recent call last): File "tflrt_delegate.py", line 17, in <module> from common_utils import * File "/edgeai-tidl-tools/examples/osrt_python/common_utils.py", line 50, in <module> tidl_tools_path = os.environ["TIDL_TOOLS_PATH"] File "/usr/lib/python3.6/os.py", line 669, in __getitem__ raise KeyError(key) from None KeyError: 'TIDL_TOOLS_PATH' (many other similar information lines)

i solved this problem by changing the code from tidl_tools_path = os.environ["TIDL_TOOLS_PATH"] to tidl_tools_path = 'path_to_tidl_tools_dir'

Did you invoke setup with below command (As described in readme)? If not, the setup script runs the commands in a new shell, so the env variables don’t get set in the parent terminal from which the script is run. source ./setup.sh
