  • OAK-D pipeline stops responding when linking nodes

Hi @jakaskerl,

I apologize for my delayed response. I am experiencing an issue with the program where it freezes after a few seconds. Upon further investigation, I noticed that the program is utilizing 2.49 Mb out of 2.50 CMX.

I have enabled DEBUG mode and here is the output that I am receiving:

Could you please help me verify if the script is correctly forwarding data from pc_nn? Also, I would appreciate it if you could clarify your previous suggestion - "Perhaps try checking if pose classification works on the host (the rest of the pipeline should remain on the device)." Do you mean that I should run the pipeline on the host instead of the OAK-D? I would appreciate any further guidance on this.

Thank you for your assistance.

    Hello erik , I'm not sure how the pipeline graph will be beneficial in this specific situation. While I understand that pipeline graphs are used to visualize pipelines, I'm uncertain how it can help us in this particular scenario. Could you please clarify this for me?

        Could you please help me verify if the script is correctly forwarding data from pc_nn?

        With pipeline graph you can see FPS of each link, so you can check whether script node is forwarding data to pc_nn output. Or is this inside Script node? If so, you can use script node logging.

          Hi @erik , thank you for your previous help. I'm new to this and I'm having trouble finding a way to view the FPS of each link. I tried using script node logging, but it's not very clear to me. I also looked at the pipeline graph to see if the script is forwarding data from pc_nn correctly, but I'm still struggling. Could you please provide some guidance or resources on how to accomplish this?

          Thank you for your assistance.

            Hi erik ,

            I wanted to give you an update regarding the version of the software I've been using. I recently discovered that I had been using version 0.0.3, but I've now updated it to version 0.0.5.

            I actually tried to install the update a few days ago, but it seems that I inadvertently installed an old version. Apologies for any confusion this may have caused.

              erik and jakaskerl ,

              I have created the pipeline graph and found out the FPS are being sent to the nodes , so what could be the possible clause of the pipeline getting freeze after few seconds?

              I am attaching screenshot of pipeline graph for your reference,

              I'm willing to share my JSON file of the pipeline graph with you. Unfortunately, I'm unable to upload the file due to a pop-up error message that keeps appearing.

              Thanks

                    Hi rb210002 , regarding freezing, it might either be an error/crash, or perhaps something is freezing due to blocking behavoiur. Feel free to prepare a MRE (max 150LoC is ideal) and we can look into it. For uploading, you can also use google drive or similar, and paste the link here.
                    Thanks, Erik

                        @erik , do I need to create the MRE on depthai GItHub issue page? Or I create it seperatly on google drive and share you the link?

                        HI erik ,

                        Here is the google drive link for the MRE, if you can confirm about creating the MRE on Depthai GitHub issue I will share the MRE on the depthai GitHub issue as well.

                        Google Drive MRE

                              I have given you access to the Google Drive. Can you please confirm if you were able to access it?

                              Hi @erik , just wanted to check if you were able to access the information I provided. If you need anything else,please let me know.
