Итак, у меня был следующий код, который, казалось, прекрасно работал, пока я не переустановил Python и Pycharm: 

from multiprocessing import cpu_count, Pool
num_cores = cpu_count()
pool = Pool(num_cores)

Это выдает следующую ошибку: 

OSError: [Errno 22] Invalid argument: 'D:\\Dropbox\\3_Master_Program\\Master_Thesis\\1_Code\\<input>'

У меня есть Понятия не имею, почему это происходит, и я буду признателен за любые советы. Я должен упомянуть, что я делаю это в среде conda, которую я создал.

РЕДАКТИРОВАТЬ: Очевидно, это связано с моей средой conda. В среде root эта ошибка не появляется
