Common Issues in the Bin Picking System

There are some common issues that people have come across while trying to use the bin picking system. Here is how to solve the most common ones before you feel the need to reach out for support Please review them in order as some have similar symptoms, but they appear in order of how common they are

Memory Consumption issues

If the system console is printing “Failed to load model, Check model path”, it is possible that you are using more GPU memory than you have. To check, open “Task Manager” and check your GPU memory limit. Your GPU memory limit must be 4.0 GB or more to run properly

To solve this problem, you must switch to a PC that has more than 4.0 GPU. If you need an immediate fix, you can temporarily switch to the CPU model, however this will run substantially slower than the GPU version.

Deep Learning Node not able to run a second time

Important

Only proceed here if you have checked your Memory Consumption first as they have similar symptoms

If you are unable to run the model a second time (The console prints “Failed to load model, Check model path”), but your GPU memory isn’t an issue, then it is possible you are missing some dll files. Please check this bin folder.

If you are missing nvrtc64_102_0.dll or nvrtc-builtins64_102.dll, please go download them from HERE

Models trained with the bottom layer removed

If there is issues finding the top layer of a dataset, use the following steps.

  1. Check your camera node and the connected file path setup. Ensure everything is set up correctly, using proper indexing or whatever may be required.

  2. In your Cloud Process node, ensure that the point cloud is coming from the camera. Make sure you have chosen Enable RGB Restore Mode and Box

  3. Add the following operations into the Cloud Process node (If they’re not there)

    • Adjust Bounding Box : This lets you expand or crop the edges of selection by a specified number of pixels. Adjust the bounding box to contain just the area useful for you.

    • Set Reference Frame : Set a reference frame for the plane

    • Dynamic Box Filter : Use to find a box in the box dataset

  4. Check your writer node is set up correctly

If that is all set up correctly, you should be able to run the flowchart with the correct output.
