Which tensorflow version to make the code work?

I know that the tf version used in this work is a bit old, so i install tensorflow 1.15, but it does not work, and throw the error:
NotImplementedError: Cannot convert a symbolic Tensor (RL_conv/strided_slice_1:0) to a numpy array.

Any idea to resolve this? Thanks.

Sorry about it. Tensorflow 1.15 is too new for this project. I think the tensorflow<=1.13 (not newer than 1.13) is OK.
