Download step "np.object" error

[BatuhanYilmaz]

Greetings,

I forked the repository and when I try to test the download step from the main project, I expected it to work from components/get_data with the script below:

mlflow run . -P steps="download"

On the other hand, I am stuch with these errors:

/home/teamx/miniconda3/envs/nyc_airbnb_dev/lib/python3.9/site-packages/mlflow/types/schema.py:49: FutureWarning: In the future `np.object` will be defined as the corresponding NumPy scalar.
  binary = (7, np.dtype("bytes"), "BinaryType", np.object)

`np.object` was a deprecated alias for the builtin `object`. To avoid this error in existing code, use `object` by itself. Doing this will not modify any behavior and is safe. 
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

I suspect that the dependencies are a bit old, since the last commit is done about two years ago.
Do you have any idea how can we solve this problem?

hello, I know a workaround by editing line 49 in the file

/home/teamx/miniconda3/envs/nyc_airbnb_dev/lib/python3.9/site-packages/mlflow/types/schema.py

binary = (7, np.dtype("bytes"), "BinaryType", np.object)

to

binary = (7, np.dtype("bytes"), "BinaryType", object)

and another solution is to install older numpy version < 1.20.0, but i don't recommend this as it will cause other conflicts.
