  3. Steps to reproduce:
    Unfortunately I have no reproducible example to share, it happened on our client side (10 clients reported the same issue on the same device)

Hi Babken,

Thanks for your information.

 

Referring to System Requirements in Install and Configure Intel® Distribution of OpenVINO™ toolkit for macOS, the supported Operating System is macOS 10.15.

 

On another note, macOS 11.5 (64-bit) was validated on Build from source OpenVINO™ toolkit. Please refer to Build OpenVINO™ Inference Engine on macOS* Systems.

Wan

Hi Wan,

 
Thanks for your reply
In my previous email there where a typo, the os version is 11.6.5

Hi Babken,

I noticed that your client loads the network using the ov_impl.load(weight*,...) method.

 

For your information, you can use the load_network() method to load the network.

For example:

from openvino.inference_engine import IECore

ie = IECore()

net = ie.read_network("alexnet.xml", "alexnet.bin")

exec_net = ie.load_network(network=net, device_name="CPU")

Hi Wan,

 

Thanks for your reply

Do you think this(loading network within ov_impl.load) is leading to pointed crush? If yes can you elaborate a little bit 

 

Warm Wishes,

Babken

Hi Babken,

 

For your information, OpenVINO™ Toolkit uses the Inference Engine to read the Intermediate Representation (IR), ONNX, and execute the model on the device.

 

Referring to OpenVINO™ Toolkit 2021.4 Inference Engine Python API, ov_impl.load() method is not available.

 

Therefore, you can use the load_network() method from OpenVINO™ Toolkit 2021.4 Inference Engine Python API to load the network.

 

For more information on the typical Inference Engine API workflow, please refer to Integrate Inference Engine with Your C++ Application.

 

 

Regards,

Wan

Hi Wan,

 

Thanks for materials.

 

The steps at our end is following

pInferPlugin = std::make_unique<Core>(XmlPath);

network = pInferPlugin->ReadNetwork(model);

pInferPlugin->LoadNetwork(network, ...);

 

And the crash (backtrace is attached)

The hardware/software info also provided

 

Can you please let me know what could be the reason of crash ? and what I'm doing incorrectly?

 

Let me know if more info is required 

 

 

Regards,

Babken

Hi 1985,

 

I have validated the Hello Classification C++ Sample from OpenVINO™ Toolkit 2021.4.1 LTS on Mas OS Big Sur 11.6.3.

For your information, the error you encountered: “EXC_BAD_ACCESS” is an exception raised as a result of accessing bad memory. Please refer to here for more information.

 

On another note, could you please execute Hello Classification C++ Sample from your end to check if you encountered the same error in this sample?

 

 

Regards,

Wan
