The following is a problem I have encountered, has been solved, written here for friends who need to refer to. My running platform is raspi, when I execute the samples, the prompt 'ImportError: No module named 'openvino', I have Executed 'xx/bin/setupvars.sh', in fact, another reason that raspi caused the failure to find 'openvino' is that the current system information, sys.path is missing a correct path, such as '/opt/ Intel/openvino/python/python3.5/armv7l', the default setting is '/opt/intel/openvino/python/python3.5', so 'ie_api.so' cannot be found, so the API provided by openvino cannot be used. of.
I answered your question in your other forum post
directory needs to get added to your PYTHONPATH, it has gone missing between 2018R5 and 2019R1 and will cause the modules to not be found.
Hope it helps,
