Run Error with Bayesian

Hello, I’ve been trying to run GA with no success (I’ll make separate post), so I thought I’d try Bayesian, and I’m getting the following error when trying to run python3 japonicus.py -b --strat PPO

The profits reported here are the profit beyond market price change;
	i.e. shown profit =  <backtest profit> - <market profit in evaluated candlestick period>;

    import _tkinter # If this fails your Python may not be configured for Tk

Any thoughts would be appreciated, Thanks!

I found the solution to my last post! 😄 Using the same method that fixed my GA error (Issue 60). After installing python properly using method you mentioned here Then running the following commands: sudo apt-get install python3.6-tk sudo python3.6 -m pip install python-tk sudo apt-get install python3-tk

Hope this helps any others that may run into this issue!

Looks like I installed manually as well like this thread, and did not include tk library from what I’m reading, now the journey begins on how to uninstall 3.6.4 and re-install properly with tk included. Anytime I try installing or downloading tk manually from terminal I get errors.

I ran into another issue on another machine I was trying to install everything fresh. I was able to install python in usr/lib using some other install method, but whenever I install or run any pip commands, everything is installed to the 3.5 python folder, for example after running the pip installer, deap is located in the 3.5 folder not 3.6. So I ran into another road block. I can run a python3.6 command, but a pip3.6 is not supported and errors. so pip3 is running from version 3.5. So frustrating.

So maybe the take away is how do I properly install python, or the necessary way for japonicus, and how to I default pip and python to run from version 3.6 when python is installed in usr/lib.

I was able to try and just download but again it installed to my 3.5 folder, and still getting the tk error

Not sure if the way I installed python is also affecting issue 60, but I actually get further results with the GA method.
