netCDF4 and ArcGIS

[StephenFricke]

I am having issues using the netCDF4 module within my python script for one of my ArcGIS tools.  The weird thing is, the tool runs fine the first time, but then when I run the tool a second time I am getting an error.  The tool is no longer able to read from the netCDF file, and gives the error when I try to read the latitude values of the file.  I then have to restart ArcGIS, and the tool then runs successfully once, but then if I run the tool again I get the same error and need to restart again.  Does anyone have any idea what is going on here?

Thank you !

I am using ArcGIS for Server 10.4 and am getting the same error when running the geoprocessing service more than once.

Fix:   If you use a Python Toolbox versus a Script tool, the problem goes away.  Hope this helps.
