Following is the error occuring when the command I input is import tensorflow_quantum:

Following are the details for the other libraries:

tensorflow==2.6.2
cirq==0.11.0

How to resolve this?

If you are using the latest version (either 0.7 or 0.6) of TFQ, you need to look at the requirements.txt and make sure you have them. It requires cirq 0.13.1 and TF 2.7.0.

Thanks a lot! This worked for me.
