You need to upgrade pymc3 to master branch, otherwise you can use the old karg sd=...

I try to use sd=…,but another error appears,RuntimeError:
An attempt has been made to start a new process before the
current process has finished its bootstrapping phase.

    This probably means that you are not using fork to start your
    child processes and you have forgotten to use the proper idiom
    in the main module:

        if __name__ == '__main__':
            freeze_support()
            ...

In fact, I have upgrated Pymc3 to 3.6, but the same error appears

HI,how about it? I also meet this trouble`````
