I have gotten this missing symbol error now in both Anaconda on Mac and in Google Colab (where the screenshot is from).
NotFoundError: /usr/lib/python3/dist-packages/tensorflow_quantum/core/ops/_tfq_simulate_ops.so: cannot open shared object file: No such file or directory
This happens when I attempt to import tensorflow_quantum after installing tensorflow==2.4.1, the newest version of tensorflow-graphics, and of course, tensorflow-quantum into fresh versions of both an anaconda env with python 3.8 and a brand new colab notebook.
I #'ed out the import line for tensorflow_quantum and the same setup had no problem with tensorflow, keras, and tensorflow_graphics, so I believe the error is coming from that install, though I have had tensorflow_quantum working properly in colab many times.
Am I missing some well understood step in the install? I swear I am simply following this guide: https://www.tensorflow.org/quantum/install
Edit: My previous success seems to have been with tensorflow==2.7.0 and tensorflow_quantum==0.7.2, so I tried that as well and had the same result.
Edit: I started a new kernel and tried this again with success. Can someone please update the installation guide on the Tensorflow site to reflect these new versions?
