Python FileNotFoundError: [Errno 2] No such file or directory: ‘objects/epsilon.pkl


The preface explains in detail

Go to WeChat and put on a fun application reinforcement learning. But go on the run and come across the problem before you go:
FileNotFoundError: [Errno 2] No such file or directory: ‘objects/ ingfix.pkl
has to learn and come up with a solution:
There is no folder or file, that is, you have access to a file that does not exist, but in fact, if the file you are accessing does not exist, the method w is used to cut access, it will create a new document, so the main problem is, there is no folder, just create a new one.
Explain in detail
Python, the OS library, is required to read and write files. Due to open the way to your files is “w”, namely file does not exist when they create a file, so the PKL documents (I mean the relative path of the PKL) does not exist is automatically created, this is not the problem, the problem is the relative path, that is the path exists, this folder does not exist as a problem. So we have to determine if this path exists. Create if it doesn’t exist.

import os
if not os.path.exists(path):

Also, note that you can only create one layer at a time for paths, meaning that the layer above your Objects exists, or you will still get an error.
