No Module named openvino and DLL load failed

[Karve__Omkar]

Hi,

I followed all the steps to install the latest OpenVino toolkit (openvino_2019.1.148) and I am trying to run the initial steps to start the inference tests. I am running everything inside a anaconda environment (the same issue occurs even if I am not in the enviromnent);

Issue1: from openvino import inference_engine as ie

This gives error that No Module named OpenVino. I have run the setup.bat files as recommended. This is resolved if I add

os.chdir("C:\Program Files (x86)\IntelSWTools\openvino\python\python3.5")

before the import. But this gives the Issue2:

Issue2: C:\Program Files (x86)\IntelSWTools\openvino\python\python3.5\openvino\inference_engine\__init__.py in <module> ----> 1 from .ie_api import * 2 __version__ = get_version() 3 __all__ = ['IENetwork', "IEPlugin", "IENetReader"] ImportError: DLL load failed: The specified module could not be found.

How can this be fixed?

EDIT1:

I thnk I solved this by adding

os.chdir("C:\Program Files (x86)\IntelSWTools\openvino_2019.1.148\python\python3.7")

before these lines:

from openvino import inference_engine as ie
from openvino.inference_engine import IENetwork, IEPlugin

But now I have a new error in line: exec_net = plugin.load(network=net)

Dear Karve, Omkar,

Happy to hear that you solved the first problem by adding os.chdir("C:\Program Files (x86)\IntelSWTools\openvino_2019.1.148\python\python3.7"). To start with here is what I would do. 

1)make sure you run bin\setupvars.bat (or *.sh)

2) Go into inference_engine\samples\python_samples and copy one of the sample folders into your own and rename it.  Please rename the contained *.py to your own name as well (matching the folder name)

3) run your code

I think most likely your environment variables are not set properly.

Thanks,

Shubha
