Reinstall torchtext with the current version of pytorch:

e.g.

conda install -y torchtext -c pytorch

or for older versions of pytorch torchtext ImportError in colab

conda install -y torchtext==0.8.0 -c pytorch

Though in general it seems in my experience that torchtext install the right version of pytorch on its own...

pip install -U torchtext

If you are using official distribution, torchtext 0.12 and torch 1.12 are incompatible and this result is expected. Please see https://github.com/pytorch/text#installation for the correct combination.

I got a similar undefined symbol: _ZTVN5torch3jit6MethodE problem.

I solved it by remaking (make -j10) the whole project (some c++ programs involved).

A possible reason could be that I reinstalled CUDA with a different version and this kind of change affected the environment (context or something).

Just some random idea... hope you can get some spirit.
