Description

Minor release.

Bug fixes:

  • Fixed bug with metric adaptation due to momentum not being resampled. Previously after the metric was updated at the end of an adaptive sampling stage with a metric adapter active the chain state momentum component was left unchanged. As under the new metric this momentum may have a very high kinetic energy (low density) and the cached Hamiltonian and gradients depending on this momentum are no longer valid this could cause the initialisation of the step size in an immediately subsequent adaptive sampling stage to fail due to the Hamiltonian at the initial state being incorrect and thus a large chain in Hamiltonian always being computed irrespective of the step size.
