Description
Trying to convert an "object" column to string fails.

Example code:

import vaex
import numpy as np

if __name__ == "__main__":
    arr = np.array([123, "test", None], dtype=object)
    df = vaex.from_arrays(test=arr)
    df['test'] = df['test'].astype('str')
    print(df.head())

Exception:

TypeError: to_string(): incompatible function argu

When running TabularPredictor.fit(), I encounter a BrokenPipeError for some reason.
What is causing this?
Could it be due to OOM error?

Feature request

As requested by some, and as @ekamioka started on this PR #244. It might be interesting to get some helper functions to use embeddings as it's not the simplest concept in deep learning.

What is the expected behavior?
Calling a few helper function to get all the correct parameters before using TabNet

Example:
In the image below the word starships should begin on a new line to avoid being split.

Terminal width is provided to determine how many columns to print. The terminal width or the total width of the column headers may be used to wrap the text in the footer.

🐛 Bug

When I train a model I want to use it offline, so I save it, but when I load it from the saved model it still pulls the online model

Is there a way to stabilise the results of the algorithm spot the diff drift detection?
In each run with same configuration and data the results of diff and p values are different.

In sklearn cross validation function, we can pass group parameter. Looking for this option here,

It would be helpful if the progress bar for model fitting could be disabled. This is particularly relevant when trying to optimize model hyperparameters, when the following occurs:

Passing a disable_pbar or similar flag to `f
