Hi, I get the following error when installing tensorflow_quantum on this container nvcr.io/nvidia/cuquantum-appliance:22.03-cirq from NVIDIA cuQuantum Appliance. (this tag because is the one with cirq 0.13.0).

>>> import tensorflow_quantum as tfq
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

The above was using tensorflow 2.11.0. Using 2.7.0 as mentioned in #714 it goes away

[jccalvojackson]

after removing the import error I get the same error as in #766 when trying to run QRL with any qsimcirq backend on a Nvidia cuquantum appliance container

@jccalvojackson Could you please give me your instructions to reproduce the result on your Nvidia cuquantum appliance container?

[jccalvojackson]

@QuantumJaeYoo the instructions are the same as those in the description of #766
