Potential incompatibility with TF2

[elchorro]

I try to run examples from help and get.:

Error in py_get_attr_impl(x, name, silent) : 
  AttributeError: module 'tensorflow' has no attribute 'placeholder'

I have found this thread suggesting TF2 has no placeholder attribute.

Hi @elchorro ,
I think sgmcmc pkg is written for Tensorflow v1 (specifically 1.13.1). So, you will have to solve this issue. For doing this please visit Tensorflow. This will solve future compatibility issues, hopefully.

best regards
