ModuleNotFoundError: No module named 'mo'

While trying to execute the following command, I am getting the below error.

sudo pot -c $INTEL_OPENVINO_DIR/deployment_tools/model_optimizer/extensions/front/tf/yolo_v3.json

Hi Rajeev,

Can you try running the below command to export the required paths for OpenVINO and re-run the command.

source /opt/intel/openvino/bin/setupvars.sh

Have you installed the pre-requisites for model optimizer? If not, Please Configure the Model Optimizer.

Regards,

Ram prasad

I have sourced the setupvars.sh prior to executing the pot command. That doesn't seem to be the reason.

python3 -c "from mo.graph.graph import Graph" works fine without issues.

[Rajeev_A_Intel]

sudo seems to be the issue.

sudo python3 -c "from mo.graph.graph import Graph" gives below error

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'mo'

The I tried the command (without sudo)

source /opt/intel/openvino/bin/setupvars.sh; pot -c $INTEL_OPENVINO_DIR/deployment_tools/model_optimizer/extensions/front/tf/yolo_v3.json

The error is as below.

The yolov3.json is used for the subgraph replacements while converting the model to IR and is not in the required format for the Post-Training Optimization tool. Please refer this Documentation and provide a config file with the parameters mentioned.

Hope this helps.
