The system cannot find the file specified

[vargasdanny]

Hi Mellissa,

I have been trying to run the docs/examples/bulk_trajgen_example.py but I am getting this error when running it:

File "C:\Users\Danny Vargas.conda\envs\pysplitenv\lib\subprocess.py", line 1207, in _execute_child
startupinfo)

FileNotFoundError: [WinError 2] The system cannot find the file specified

I am running it in Windows 10, python=3.6 and use spyder 5.0 to run the code. I followed all the instructions from the github repository and your paper but I could not make any progress solving it. May you please help me with this issue. Many thanks.
Danny

Dear Melissa,

I have the same problem. I am working with Windows 10, python 3.6 and running in anaconda prompt. Any idea what the issue could be?
Kind regards,

Elemér

It turned out the code was looking for something in 'C:/hysplit4/exec' and my hysplit folder name did not have the number 4 in it. So I added the number 4 to the folder name and it worked. I hope that helps everyone else.

Or you can just change the last key word:
"The final keyword argument is the location of the HYSPLIT trajectory executable. On Windows systems, this will usually be 'C:\hysplit4\exec\hyts_std' (default value). PySPLIT calls this executable to calculate trajectories."

Hi Kevin,
Thank you so much for the suggestions. Based on your comments I could solve it. Besides adding the number 4, a backslash "/" was missing in the working directory, so at the end, it worked out and now looks like this:
working_dir = r'C:/hysplit4/exec/

I hope it helps others as well.

Cheers,
Danny

Hello All,
Thank you for the previous suggestion to rename "/hysplit" folder to "/hysplit4". However, I found another issue during plotting of clusters using "hysplit_clustering.py". The error is <[Errno 2] No such file or directory: 'CLUSLIST_7'>, as there is no file named CLUSLIST_7. Is anyone faces same issue? Could you please help me to solve this error.
Thank you in advance,
Best,
Soni

Hi Soni,
This issue was already answered, check this #50
You get the CLUSLIST_7 file from running the HYSPLIT software from your computer. The number 7 is the number of clusters you wish to run, e.g. if you choose 5 clusters from the HYSPLIT interface after running you will get CLUSLIST_5. Hope it helps.
Cheers,
Danny
