function( ) got an unexpected keyword argument 'sample'

[ManojVellatoori]

Hi, I tried SingleImputer on one of my datasets and it is failing, if there are missing values in the column that should be predicted.

And then I tried to run the example given in your tutorial: Link: https://kearnz.github.io/autoimpute-tutorials/ (Getting the Most out of the Imputer Classes: Part III) I tried to run SingleImputer

I'm running into the same error. Auto-assigning NUTS sampler... Initializing NUTS using jitter+adapt_diag...

Hi @ManojVellatoori @marcelkore

This problem has been addressed in a previously closed issue and is also discussed in the README.

Bayesian-based methods in Autoimpute work with pymc3==3.5 and pymc3==3.6. The latest release of pymc3 is 3.7, which breaks Autoimpute. I'm currently working on a fix to get Autoimpute back in line with the latest pymc3, but I do not have an ETA.

Your best option is to install Autoimpute using the requirements.txt file. Also best to do this in a virtual environment.

Please let me know if this fixes the issue.

Joe
