Error Executing Windpower Module with Downloaded SRW Files

When following the documentation example for PySAM.ResourceTools.FetchResourceFiles (github.com/NREL/pysam/blob/main/Examples/FetchResourceFileExample.py), the script successfully downloads the wind SRW file, but fails to execute the Windpower module. I receive the following error (using PySAM 4.1.0):

Exception: windpower execution error.
        exec fail(windpower): failed to read local weather file: number of columns in header line 5 must match line 3: 4 required but 9 found

I've attached a screenshot of the SRW file in question.

 

I do not encounter the same issue with downloading solar files and executing the PvWatts module.

As a workaround, converting the SRW file to a wind data dictionary (ResourceTools.SRW_to_wind_data) and assigning that to the 'wind_resource_data' variable seems to work (at least in this example). Is there something more obvious that I'm missing when downloading the SRW files and trying to execute them directly, or should I be converting all of them to data dictionaries as above prior to executing the Windpower module? If the latter, is there a similar way to do this in PySSC (currently use 'ssc.data_set_string( data, b'wind_resource_filename', bytes(wtk_fp, encoding = 'utf8')), but not finding anything in a quick search of the documentation for setting resource_data this way)?

Thanks in advance.
 

Hi Paul,

Thanks for the quick response. Stripping the trailing commas seems to work; just didn't expect to have to do that since in previous PySAM releases that co-workers use it isn't necessary.

Thanks again and no need for further investigation.
