Function get_available_demos crashes if a dataset's num-tables or size-MB cannot be found

[npatki]

Environment Details

• SDV version: 1.0.0 (in progress)
• Python version: 3.8
• Operating System: Linux (Colab Notebook)

Error Description

The get_available_demos reads datasets from the public S3 bucket and uses meta information to read and fill out the num_tables and size_MB. If this information isn't found, the entire get_available_demos crashes.

Proposed Fix

Instead of crashing the entire function, the row that describes the dataset should include NaN for the num_tables and size_MB columns.

dataset_name	size_MB	num_tables
KRK_v1	0.07	1
adult	3.90	NaN
alarm	NaN	NaN
