t8ch fixes

[twiecki]

Thanks @t8ch, was this throwing an error before?

[t8ch]

Hi. Yes, I got

I think the SMC Sampler is simply not implemented yet.

@luke14free Are you still active on this project? Looking for help maintaining?

[luke14free]

I opened my own company and wish I had more free time to follow everything @twiecki 🙃 but @t8ch is trying to help me maintain the project. I'll look into active issues soon nevertheless

[t8ch]

@twiecki do you think it makes already/still sense to migrate the code to pymc4 and implement changes and new features there?

[twiecki]

No, not yet I think.

@luke14free How do you feel of moving this to its own org or the pymc3 org and giving access to some other people (like me) who can help maintaining?

[luke14free]

it makes 100% sense but I am not confident this library has the quality required to be in the pymc3 org. I am nevertheless happy to have you/tim take over/contribute.
