"Symbol not found in flat name space" in MacOS (macbook pro M1) when importing ctcdecode

[JoseEliel]

Hi!
I've been on a somewhat problematic path of trying to install ctcdecode on MacOS with an M1 MacBook pro.
I had to use GCC 12 instead of clang for the installation to work at all.
After pip seems to install ctcdecode, importing it results in the error:

ImportError: dlopen(/opt/homebrew/Caskroom/miniforge/base/envs/rusocr/lib/python3.8/site-packages/ctcdecode/_ext/ctc_decode.cpython-38-darwin.so, 0x0002): symbol not found in flat namespace '__ZN3c1010TensorImpl17set_autograd_metaESt10unique_ptrINS_21AutogradMetaInterfaceESt14default_deleteIS2_EE'

I have torch, torchvision and torchaudio installed, and I've tried importing torch before importing ctcdecode to no avail.
I tried installing torch from source, but pip can't find the package when I give the no binary option.
