Linux, Python, C ++, Brain2 and errors.

[PiotrBujakowski]

Hi.

I try to make and run first time AI Neural Network on my computer.
Knowledge Python is basic.

I'm using Linux Ubuntu.

I install whole in system using apt.
When show communicate about pip, then I'm doing that.
[Is a lot of problems with right file names and compatibility.]

I try to configure to direction in home catalogue [advice from Gemini].
Port 65432 is unblocked in firewall.

Helpful is Gemini, but can't solve problems what I have now.

Please help me with that.

Python engine:
