Description
In a few places, we remove the imaginary part for hermitian matrices.
It's nice for the user, but it breaks a few cases:
isherm
check breaksjax.jit
and tensorflows does not support casting for auto-differentiation. The solution we had when tensorflow was added was to detect it (noreal
method). But this did not fixjit
as seen in qutip/qutip-jax#34.This add a setting that is checked first, so after
qutip.settings.core["auto_real_casting"] =False
all these checks are removed andjit
works.
