When I try to run the model I get a numpy error in Flow Projects

[Ildemselcuk]

We use it to simulate the model we created in flow projects. After running this script "python3 ../flow/visualize/visualizer_rllib.py data/trained_ring 200 --horizon 2000 --gen_emission", I get the numpy error in the image. All Pip packages are the same as in the flow projects "requirements.txt".

but I got a new error:

To add, although I solved the problem with keys, when I ran the simulation, I found that I couldn't generate an XML file, and there is only CSV file
