fix: directory creation on pulling data

[sssilvar]

Closes #10579

[skshetry]

There is no exist_ok=True in os.mkdir. That is in os.makedirs.

This should either be:

Suggested change

	os.mkdir(d, exist_ok=True)
	try:
	os.mkdir(d)
	except OSError:
	if not os.path.isdir(d):
	raise

or,

Suggested change

	os.mkdir(d, exist_ok=True)
	os.makedirs(d, exist_ok=True)

I'd prefer the first one as makedirs calls os.path.exists() on all the parents of the path.
