Could not connect to Omni sci in knn_model.py #11

Open jakerbrown opened 4 years ago

jakerbrown commented 4 years ago

When running the modified version of knn_model.py, I got the following error, related to connecting to OmniSci:

You might not be connecting to the right port! Please connect ti the backend port in your script not the frontend. Refer here under "Running scripts" section for instructions on how to find backend port: https://github.com/cga-harvard/GIS_Apps_on_HPC/blob/master/Using%20FASRC%20Geospatial%20Resources.pdf

Should I not have changed the port numbers already in the script with my requested job’s port?

Yes, you should change the port to your job port but you are not providing the correct post from your job. Did you get the port number from output.log file as mentioned in the pdf?
