[Issue] NumPy version in mlfinlab is incompatible with TensorFlow

[kinivi]

Problem:
mlfinlab 1.0.1 requires numpy==1.20.1, but tensorflow 2.4.1 requires numpy~=1.19.2.
That is why LSTM layers and other TensorFlow functions don't properly work with NumPy 1.19.5. (see here)

Solution:
Recommend to downgrade NumPy to 1.18.5

Thanks @kinivi.

At the moment Numpy's latest release has caused some serious problems with CVXPY and TF. We have updated our versions to the latest stable versions that we can get it to work with but 0.1.20.1 doesn't work with the latest TF. We are waiting for TF to update its dependencies.

We have removed TF from the dependencies in the mean time.
