Exact pybind11 commit PyTorch 1.9.0 was built against

Hi Everyone,

I am getting a runtime error with my JIT/ATen code that seems to indicate that the pybind11 version that I am building against is not the correct one that PyTorch 1.9 was built against.
I am struggling to find any information on where to find the pybind11 version used, can anyone help please?

Many thanks and with best wishes


This is the currently tagged pybind11 version:
