All of the sudden problem with generate_bulk traj

[NBolohanUO]

Hey all,

Out of nowhere, I have started receiving this error on scripts that previously would run no problem. The problem occurred after I deleted old trajectories but I'm confused because the problem is happening when I try to generate a new trajectory. The error is as follows:

Traceback (most recent call last): File "C:\Users\Noah Bolohan\AppData\Local\Programs\Python\Python39\Scripts\PySplit\MPBLDDJuly2005Model3BugFix.py", line 76, in pysplit.generate_bulktraj(basename, hysplit_working, output_dir, meteo_dir, years, months, hours, altitudes, coordinates, run) File "C:\ProgramData\Anaconda3\envs\pysplitenv\lib\site-packages\pysplit\trajectory_generator.py", line 165, in generate_bulktraj call(hysplit) File "C:\ProgramData\Anaconda3\envs\pysplitenv\lib\subprocess.py", line 339, in call with Popen(*popenargs, *kwargs) as p: File "C:\ProgramData\Anaconda3\envs\pysplitenv\lib\site-packages\spyder_kernels\customize\spydercustomize.py", line 108, in init super(SubprocessPopen, self).init(args, **kwargs) File "C:\ProgramData\Anaconda3\envs\pysplitenv\lib\subprocess.py", line 800, in init restore_signals, start_new_session) File "C:\ProgramData\Anaconda3\envs\pysplitenv\lib\subprocess.py", line 1207, in _execute_child startupinfo) FileNotFoundError: [WinError 2] The system cannot find the file specified

I'm not really sure how to read this error and solve my problem, but it feels very much out of my reach. Could someone help me solve this?

To add, I can successfully run the given trajectory_generator file no problem, and here is my code. I've tried to copy-paste from working scripts as much as I could but as soon as I get to the generate_bulktraj, I get my above error.

I was able to fix this issue by having my meteo_dir folder separate from my hysplit_working folder. This wasn't an issue in the past but I suppose all of the sudden it was!
