Question/Issue:
CNN-GRU model failing to train successfully

Project ID:
896583

Context/Use case:
During training

Summary:
I am trying to train a CNN-GRU classifier to compare to CNN only, but when I try to train the GRU it gets stuck in an infinite loop attaching to the job after packing the Tflite model.

Steps to Reproduce:

  1. [Step 1]
  2. [Step 2]
  3. [Step 3]

Expected Results:
Model training completes

Actual Results:
Infinite hang with message “Attaching to job #######…”

Reproducibility:

  • [X] Always
  • [ ] Sometimes
  • [ ] Rarely

Environment:

  • Platform: Arduino Portenta H7 Cortex-M7
  • Build Environment Details: [e.g., Arduino IDE 1.8.19 ESP32 Core for Arduino 2.0.4]
  • OS Version: [e.g., Ubuntu 20.04, Windows 10]
  • Edge Impulse Version (Firmware): [e.g., 1.2.3]
    To find out Edge Impulse Version:
  • if you have pre-compiled firmware: run edge-impulse-run-impulse --raw and type AT+INFO. Look for Edge Impulse version in the output.
  • if you have a library deployment: inside the unarchived deployment, open model-parameters/model_metadata.h and look for EI_STUDIO_VERSION_MAJOR, EI_STUDIO_VERSION_MINOR, EI_STUDIO_VERSION_PATCH
  • Edge Impulse CLI Version: [e.g., 1.5.0]
  • Project Version: [e.g., 1.0.0]
  • Custom Blocks / Impulse Configuration: [Describe custom blocks used or impulse configuration]
