In case this is an issue for you and downgrading Tensorflow is not an option, here is a hack:

delete tensorflow/core/kernels/libtfkernel_sobol_op.so altogether. This operator is a special purpose op in classic computer version for edge extraction and for 99.99% of the use cases of TF (training DNN) you won't need this operator.

This simple quickfix worked for me! I wasted a lot of time trying to find a solution! – lifezbeautiful Jul 20 '21 at 12:36

Worked for me when uninstall/install did not! To be on the safe side, I just renamed it to a backup file – aqua Feb 26 '22 at 19:54

Looks like it is the following issue (same symbol _ZN10tensorflow8OpKernel11TraceStringEPNS_15OpKernelContextEb is missing): https://github.com/tensorflow/text/issues/385

Did you try to update Tensorflow?

Bit annoying, but can you show output of this command `python3 -c 'import tensorflow as tf; print(tf.__version__)'`? – CPPCPPCPPCPPCPPCPPCPPCPPCPPCPP Dec 28 '20 at 17:11
According to github it looks like a problem only with version 2.3.0, but not 2.4.0. – CPPCPPCPPCPPCPPCPPCPPCPPCPPCPP Dec 28 '20 at 17:25

I have installed 2.3.0 the problem solved :) – Dayanand Dhumala Dec 30 '20 at 13:44
@dayanand-dhumala Yay. It was nice to help you. – CPPCPPCPPCPPCPPCPPCPPCPPCPPCPP Dec 30 '20 at 13:46

`pip uninstall tensorflow` to uninstall, and `pip install -U tensorflow==2.3.0` to install a working version. – Joe Eifert Jan 08 '21 at 15:56
