Thanks Junpeng, this disappeared when updating.

Using pip, I reinstalled from git, which solved the issue. Sorry, I had briefly checked that I was up to date. Having installed a while ago, that was apparently with the pip repositories and not with git.

Also, regarding my other question, I discovered [your presentation](https://discourse.pymc.io/t/advance-bayesian-modelling-with-pymc3/1439) and the part on multivariate statistics and will try to work through it. There are lots of tricks in it that will certainly apply to my data.

Best,

Falk
