https://github.com/mjacar/pytorch-trpo 21 I run example.py 6 in this project and came across several problems: one is unexpected argument create_graph
change


dict iteration methods,

xrange to range and
remove create_graph=True


made the trpo cartpole example work in python3.
But I wanna know what does create_graph do for us? And whether this argument has already been removed? Thanks.
