Aggregated Temperature Product: Permission error with temporary file

[mphemming]

File ~\\Code\python-aodntools-master\python-aodntools-master\aodntools\timeseries_products\aggregated_timeseries.py:363 in main_aggregator shutil.move(temp_outfile, os.path.join(output_dir, ncout_path))

File ~\Anaconda3\lib\shutil.py:812 in move os.unlink(src)

PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\Code\python-aodntools-master\python-aodntools-master\tmp9bpsj45m.nc'

I use Spyder/Jupyter notebook and I often get this error when modifying a NetCDF file while a file of the same name is currently imported into the workspace.

The LTSP is created successfully, but the temporary file is left unmodified.

So the issue is that the temp file is still open in Spyder, meaning that shutils cannot move the file at the end of the main aggregator function.

I edited line 214 to include 'fd' as output: _, temp_outfile = tempfile.mkstemp(suffix='.nc', dir=output_dir) to fd, temp_outfile = tempfile.mkstemp(suffix='.nc', dir=output_dir).

I can then close the object adding the following code to line 355 prior to using 'shutil.move':

os.close(fd)

This now works without an error for both 'aggregated_timeseries.py' and 'velocity_aggregated_timeseries.py'. Perhaps the AODN can consider editing the code to include this.

Thanks @mphemming The most efficient way to propose changes to the code is to fork the repository, commit your changes, and submit a Pull Request. Then we can review it and merge it in once finalised. Does that work for you?
