STINNER Victor <vstin...@redhat.com> added the comment:
The screenshot says "OSError: [WinError 87] Falscher Parameter" at
Lib/subprocess.py:1178 which is this call:
hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
# no special security
None, None,
int(not close_fds),
creationflags,
env,
os.fspath(cwd) if cwd is not None else
None,
startupinfo)
According to the traceback, the call is:
subprocess.check_output([execStr,"-3",self.geofile,"-o",self.vtkFile])
Can you please dump these parameters? Are they all strings?
IMHO execStr, self.geofile or self.vtkFile is not a valid string and it's a bug
in your code.
