Support for columns contains only numbers.

[gszecsenyi]

In the case where the column names contain only numbers, typically when scaling the data, the code doesn't work well because the first value of the variable will be a numeric value, not a string, to which you cannot append a string later.

The executed commands are:

synthesizer = SingleTablePreset(
metadata,
name='FAST_ML'
)

synthesizer.fit(
data=test_df
)

synthetic_data = synthesizer.sample(
num_rows=500
)

synthetic_data.head()

The output:

File [~/GitHub/ml_network_analysis_experiments/.venv/lib/python3.9/site-packages/rdt/transformers/base.py:367](https://file+.vscode-resource.vscode-cdn.net/Users/**********/GitHub/ml_network_analysis_experiments/~/GitHub/ml_network_analysis_experiments/.venv/lib/python3.9/site-packages/rdt/transformers/base.py:367), in BaseTransformer._set_seed(self, data) 365 hash_value = self.columns[0] 366 for value in data.head(5): --> 367 hash_value += str(value) 369 hash_value = int(hashlib.sha256(hash_value.encode('utf-8')).hexdigest(), 16) 370 self.random_seed = hash_value % ((2 ** 32) - 1) # maximum value for a seed

This is why this modifications are needed.

self.column_prefix = '#'.join(map(str, self.columns))

and

hash_value = str(self.columns[0])
