I ran into the same issue just because I had the serial monitor opened

Im just copying all files and subfolders from an specific directory using the function distutils.dir_util.copy_tree in Windows:
from distutils.dir_util import copy_tree
from datetime import datetime
directories_to_backup = {
'folder_a' : 'e:\\folder_a',
}
now = datetime.now()
backup_name_folder = now.strftime("%Y%m%d-%H%M")
for name_folder, path_folder in directories_to_backup.items():
print(f'Backuping up the folder {name_folder}')
backup_full_path = f't:\\zzzBackup\\{backup_name_folder}\\{name_folder}\\'
copy_tree(path_folder, backup_full_path)
it works fine till it get to some specific file and rise the following error:

How can I update the permissions in windows so my script would be able to read and copy the files?

When I try using pip install to get GDAL I run into an error about a file not found. I went to the location and there is definitely no folder there but shouldn't the installer install the folder it needs first?

I followed following Github issue thread but din't find any luck.
Could any body tell whats went wrong ?
Thanks
Turns out that there was existing venv-nerapi . Deleting existing virtual env and re-creating it worked fine.
I am trying to call a function using subprocess.Popen as:
proc = subprocess.Popen(["/usr/local/bin/qstat", "-u", "rudrab"],stdout=subprocess.PIPE)
numjobs = proc.stdout.read()
which is giving error:
Traceback (most recent call last):
File "genpos.py", line 159, in <module>
proc = subprocess.Popen(["/usr/local/bin/qstat", "-u", "rudrab"],stdout=subprocess.PIPE)

FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/bin/qstat'
but qstat is in my path:
which qstat
/usr/local/bin/qstat
what I am doing wrong here?
