Openvino extension

[Erwin8]

Tried to make my own text spotting application, but did not work with the "text-spotting-0003-detector" and the "text-spotting-0003-recognizer-decoder" model on windows. Could not load it into the IECore().

Think it is the extension: "RuntimeError: Cannot create Range layer ReduceMin_589/axes id:445". How do I add the extension on windows 10. Did not find the .so file in the system?

Hi Erwin,

Greetings to you.

For your information, OpenVINO™ Toolkit also provides one text spotting demo and I’ve validated that demo works well with the text-spotting-0003-detector, text-spotting-0003-recognizer-encoder and text-spotting-0003-recognizer-encoder models on OpenVINO™ 2021.2  without specifying any extension library.

Please note that text-spotting-0003 model can only work on OpenVINO™ 2021.2. I’ve also validated that the demo failed to work with text-spotting-0003 model on various versions of OpenVINO™ (2020.1, 2020.4,2021.1) and resulted in getting different runtime errors. I got the exact runtime error as you when running the demo on OpenVINO™ version 2020.4.

You may refer to the Release Notes for Intel® Distribution of OpenVINO™ Toolkit 2021 under the section “Open Model Zoo”.

https://software.intel.com/content/www/us/en/develop/articles/openvino-relnotes.html

Please check the OpenVINO™ version that you’re using. It is always advisable to upgrade OpenVINO™ to the latest version or use the Model Downloader in OpenVINO™ that you’re using to download the model. If you’re already using the latest OpenVINO™ version, please do me a favor to try running the text spotting demo and share the result with me.

Hi Peh,

Thanks for the answer.

I installed the Openvino 2021.2 version (Windows 10) but am using Anaconda and the last version there is 2020.4. So I think Anaconda only takes into account this version.

Is there some way to have anaconda which works with the latest version of Openvino?

Regards

Erwin

Hi Erwin,

You can install the runtime package for the latest version of OpenVINO™ version with these commands:

conda install -c anaconda python=3.7

conda install openvino-ie4py -c intel

OR

You can create a virtual environment and install the runtime package for the latest version of OpenVINO™ version with these commands:

conda create -n <name> python=3.7

conda activate <name>

conda install openvino-ie4py -c intel

Hi Peh,

Great, it works with creating a new environment. The update of the old one did not work, maybe I have to uninstall openvino and then reinstall it.

However, an error occurred with the new OpenVion version:

not_supported_layers = [l for l in self.network.layers.keys() if l not in supported_layers]
AttributeError: 'openvino.inference_engine.ie_api.IENetwork' object has no attribute 'layers'

So, with the new version, I no longer have to search for supported layers, right? 

Regards

Erwin

Hi Erwin,

This property, 'ie_api.IENetwork.layers' is deprecated and removed in OpenVINO™ version 2021.2. Please refer to this thread that had well discussed the same issue before. There is also a shared workaround available in that thread.

You can try running your application without searching for the supported layers or use the nGraph function's get_ordered_ops method.
