As part of
DM-14305 upgrading Eigen to 3.3 we need to transition to a version new enough that pybind11 supports it. The earliest version of Eigen that our pybind11 supports is 3.2.7. This intermediate step is required in order to release a version of ndarray that no longer uses EigenView for pybind11, and thus allows us to switch to the standard pybind11 wrappers.
I will go to 3.2.10, the latest 3.2 release, in order to get as many bug fixes and other improvements as we can.
