NotImplementedError: Cannot convert a symbolic Tensor (2nd_target:0) to a numpy array

For me, the above issue occurred when upgrading from numpy 1.20 and using ray's RLlib, which uses tensorflow 2.2 internally. Simply downgrading with version numpy==1.19.5 solved my problem.

But there is no numpy in requirements.txt
Where should I change version?
