Hi,

We are converting our yolov5 model with your tool (http://tools.luxonis.com/).

There is option to convert it with openvino 2021.4. But the openvino of using 2021.4 is not working. it is no matter setting or not. only converted with 2022.1. So there is some issue

\depthai-experiments\gen2-yolo\device-decoding > python main_api.py -m bestopenvino_2022.1_6shave.blob -c best.json

Below is the error message. And i changed the name of .blob file from 2022.1 to 2021.4 then. it is working now.

      Hi RyanLee
      It looks to me the blob path was incorrectly specified when using the 2021.4 blob.

      Thoughts?

          Oh, the version of blob when we are using 2022.1. it is not working. But if i changed the file name to bestopenvino_2021.4_6shave.blob (openvino version 2021.4 not 2022.1). Then it is working. I think that the openvino version is hardcoded in \depthai-experiments\gen2-yolo\device-decoding codes.

          And even though i checked "Use OpenVINo 2021.4" in your convertining tool, it is only output as the version 2022.1.

          Thought??

          Best regards,

          Ryan.

              Hi RyanLee
              You can set the desired openVINO version using: pipeline.setOpenVINOVersion(dai.OpenVINO.Version.VERSION_2021_3)if you think that's causing the issue you are experiencing.

              Thanks,
              Jaka

                  jakaskerl

                  Thank you for your quick response.

                  And where do i need to put this in \depthai-experiments\gen2-yolo\device-decoding\mainapi.py file?? I tried it to add in the mainapi.py file. but it is not working. So i need you some more help.

                  <the code i would like to put>

                  pipeline.setOpenVINOVersion(dai.OpenVINO.Version.VERSION_2022_1)

                  Best regards,

                  Ryan.

                      Hi RyanLee
                      Main_api.py file right after the pipeline is instantiated. This would be line 63.
                      Let me know if it works. If it doesn't, what errors are you getting?

                      Thanks,
                      Jaka

                          Hi jakaskerl

                              Hi RyanLee
                              I still think you are incorrectly specifying the blob path.

                              Note this:

                              RyanLee No blob found at best__openvino_2022.1_6shave.blob. Looking into DepthAI model zoo.

                              Can you check please?

                                    I think that in your code, there is some hardcoded with 2021.4 now.

                                    Look at below.

                                    https://artifacts.luxonis.com/artifactory/blobconverter-backup/blobs/best__openvino_2022.1_6shave.blob_openvino_2021.4_6shave.blob

                                    And i did one more test. i changed the version of .blob from 2022.1 to 2021.4. And then run like below. Then it is working. I just changed the version name of .blob file and run with the version of 2021.4.

                                    PS C:\Users\ryan\depthai-experiments\gen2-yolo\device-decoding> python main_api.py -m bestopenvino_2021.4_6shave.blob -c best.json

                                    It seems the file name of 2022.1 is not working because in your code there is some hardcoded with 2021.4.

                                    How do you think?

                                    Best regards,

                                        It can't find the given path name, so it tries to download the blob from the backup. Could you share the .zip downloaded from the tools.luxonis.com (should contain json, bin & xml, blob)?
