Bug description
I'm trying to run the Irrigation Classification Notebook, but I'm getting the following error:
When I run " run.reason", the log file looks as follows:
"RuntimeError: Failed to run op stack_landsat_bands in workflow run id cb40bb24-ebf0-4f82-96af-c87fa9df479c for input with message id 00-cb40bb24ebf04f8296afc87fa9df479c-7f94920eace13cef-01. Error description: <class 'RuntimeError'>: self._exception\npebble.common.ProcessExpired: Abnormal termination\n."
I also tried to change the buffer size to download a smaller image, but I'm getting the same error.
Can you also advise on how to customise the workflow for my study area ? I get see that the model was calibrated using training samples collected in a field in Nebraska. How do I use my own model ?
Hi @ZoloKiala , it looks like you have run out-of-memory. If you are running this in a VM, you are able to see OOM messages with dmesg (you may need to run this as root). This specific model is a simple logistic regression with parameters you can adjust (please see the parameters in the https://microsoft.github.io/farmvibes-ai/docfiles/markdown/workflow_yaml/farm_ai/water/irrigation_classification.html ). If you want more sophisticated models, you can express them as Onnx files (see an example as in https://github.com/microsoft/farmvibes-ai/blob/main/notebooks/crop_cycles/crop_cycles.ipynb). Please let us know if you have any further question.
@edrodrigues-ag Thanks for your prompt reply. I'm using WSL. My computer has 10 processing cores (I think it's good enough). Should I move to a VM ?
I will try to more sophisticated models as suggested.
WSL should be fine. Please check the memory amount allocated to WSL: free -h. 32 GB is recommended.
I increased the memory amount allocated to WSL. It's working now. Thank you very much!
