"Kind of like"? So it might be different? How much different?

[snip irrelevant code]

Please try to cut your code down to the minimum necessary to demonstrate 
the problem.

You can simplify Windows pathnames by using forward slashes.

Of course it does not work. You have commented it out.

What says "it" doesn't have sufficient memory? What's "it"? You may have 
seen the error, but we haven't. Please COPY AND PASTE the exact error 
message, IN FULL, and describe where it comes from:

* is it a Python traceback?

* something printed directly to the terminal but not a traceback?

* Blue Screen of Death?

* a message in a GUI alert?

* something else?

No.
