ImportError: cannot import name '_compat' from 'cirq' (unknown location)

Question

I am trying to import the module tensorflow_quantum as follows

>>> import tensorflow_quantum as tfq

But, I get the following error.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/conda/lib/python3.8/site-packages/tensorflow_quantum/__init__.py", line 18, in <module>

    from cirq import _compat
ImportError: cannot import name '_compat' from 'cirq' (unknown location)

I have already installed cirq. It works as follows

>>> import cirq
>>> 

Any help please?
