QUESTION
In following this tutorial, I am receiving the following error:
ValueError: prefix tensor must be either a scalar or vector, but saw tensor: Tensor("Placeholder_2:0", dtype=int32)
The error originates from these lines:
...ANSWER
Answered 2017-Jul-24 at 01:52I met the same problem with the version of tensorflow is 1.2.+.
When i changed it to 1.1.0, the problem resolved.
I think it because the API of rnn_cell.zero_state makes arg batch_size must be a scalar or vector, but not tensor.
So, if you change batch_size to scalar, e.g. 128, the problem also could be resolved.

Install rl-agents
You can use rl-agents like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
