TypeError: set_color() got multiple values for argument 'alpha' in Simple-Crypto

[marwanihab]

Running the train.py using the simple crypto scenario gives me this error, I have tried printing out the value of the alpha but all I got was only one value so how to solve this ?

`Traceback (most recent call last): File "train.py", line 193, in train(arglist) File "train.py", line 153, in train env.render() File "/Users/Maro31/bachelor/multiagent-particle-envs/multiagent/environment.py", line 235, in render geom.set_color(*entity.color, alpha=0.5) TypeError: set_color() got multiple values for argument 'alpha'```

I got the same error too, but I have no solutions. Have you solve it?

Looking for an answer to this as well.

I think the problem is the parameter setting of world.dim_c in simple_crypto.py.In this file,I tried changing the parameter of world.dim_c to 3, the program didn't report errors and the anmination demonstration effect is normal.

I changed multiagent-particle-envs/multiagent/environment.py，Line 234 to geom.set_color(entity.color[0],entity.color[1],entity.color[2],0.5)，and it could run correctly.
