shortest path to upgrade to openvino 2022.1

erik

I installed depthai environment a while ago (before 2022.1) so when I run oak depthai the virtual environment I installed will automatically select the 2021.4 version to run the blob. And the following is one example I encounter:

1. I use blobconverter and select 2021.4 to compile my blob
2. when I run the depthai program (including your code to report the blob.version), the error message shows up as below:

   #your code report blob parameters
   blob.version= Version.VERSION_2021_4
   Inputs
   Name: right, Type: DataType.U8F, Shape: [320, 240, 3, 1]
   Name: left, Type: DataType.U8F, Shape: [320, 240, 3, 1]
   Outputs
   Name: output, Type: DataType.FP16, Shape: [320, 240, 2, 1]
   #error messages below
   [184430106183EB0F00] [32.457] [NeuralNetwork(8)] [warning] Network compiled for 4 shaves, maximum available 12, compiling for 6 shaves likely will yield in better performance
   [184430106183EB0F00] [32.469] [NeuralNetwork(8)] [error] Neural network blob compiled with uncompatible openvino version. Selected openvino version 2021.4. If you want to select an explicit openvino version use: setOpenVINOVersion while creating pipeline.
   [184430106183EB0F00] [32.470] [NeuralNetwork(8)] [error] Neural network blob compiled with uncompatible openvino version. Selected openvino version 2021.4. If you want to select an explicit openvino version use: setOpenVINOVersion while creating pipeline.
   

   As you can see, something is wrong with the error message: it said the blob was compiled with uncompatible version and indicated that I am using 2021.4 but as you can see the blob.version reported 2021.4. (And I did compile it with 2021.4 blobcoverter!) What am I missing? Please advise. Thanks. (Do I need to upgrade my depthai to align to openvino_2022.1?)

MRE is here.

Thanks.

what was done:

1. try to simplified mre.py further.
2. try to include the blobconverter script in the mre.py but failed, please take a look what's missing
3. try to create CLI script as bc.bat but failed, too. Please take a look what's missing

the model.blob was generated by manual feeding in model.onnx and clicking through your online blobconverter website and now renamed to model_orig.blob

Thank you for your help

That's good to know.

By the way, so far I am not able to perform blobconverter over the script, could you help to take a look what's wrong bleow:

import blobconverter

blob_path = blobconverter.from_onnx(
    model="model.onnx",
    data_type="FP16",
    shaves=6,
    optimizer_params=[
        "-ip U8",
        "-op FP16",
    ],
)

And where to put the openvino version 2021.4 in the script?
If I run the above script, the error message is as below:
