It seems like there is something goes wrong with the mpi4py, but i'm already use the version==3.0. This error happened in win10 system.

replace File "D:/Desktop/evolution/code/WANN/wann_train.py", line 233, in mpi_fork
subprocess.check_call(["mpirun", "-np", str(n), sys.executable] +['-u']+ sys.argv, env=env)

[yachenkang]

There's no longer an error! Thanks!

[yachenkang]

replace File "D:/Desktop/evolution/code/WANN/wann_train.py", line 233, in mpi_fork
subprocess.check_call(["mpirun", "-np", str(n), sys.executable] +['-u']+ sys.argv, env=env)

There's another problem. Now that the program just stack in line 233 and can not get through.

[MANXIU]

not stack ,its just begin to calculate the model,that,s how the code works

[yachenkang]

So I can only wait until it ends? How long should it takes? Is there a progress bar?

[yachenkang]

Oh, I found out where the problem is. I used to use the spyder to run the file directly. When I run in the terminal, the program runs normally. Thank you for your help!

I have the same error when running on windows, but it works when running on ubuntu.
