No features can be generated from the specified primitives

Question

Why is this error being generated?

How can resolve it?

import featuretools as ft
import pandas as pd

# Define the column headers
column_heads = ['UniqueIndex', 'AminoAcid', 'HECcode',
                'R13distance', 'R14distance', 'R15distance',
                'NeighborCount4Angstrom', 'NeighborCount45Angstrom',
                'NeighborCount5Angstrom', 'NeighborCount6Angstrom',
                'NeighborCount8Angstrom', 'HBondsCount']

# Read the CSV file, making sure to set delim_whitespace=True if your data is whitespace delimited
proteins_df = pd.read_csv(filepath_or_buffer=r'C:\git\_origina_data\_v2.full.regular.unique_id.txt',
                          delim_whitespace=True, names=column_heads, header=None)

# Set the 'UniqueIndex' column as the index of the DataFrame
proteins_df.set_index('UniqueIndex', inplace=True)

# Initialize the EntitySet
es = ft.EntitySet(id="proteins_entity")

# Add the DataFrame to the EntitySet, using the 'UniqueIndex' as the unique index
es = es.add_dataframe(
    dataframe_name="proteins_df",
    dataframe=proteins_df,
    index='UniqueIndex'  # Make sure this matches the name of the index column
)

# Specify which primitives to use if the default ones are not suitable
# You can get a list of all primitives with ft.primitives.list_primitives()

# Now you can run deep feature synthesis (dfs) to create new features
feature_matrix, feature_defs = ft.dfs(
    entityset=es,
    target_dataframe_name="proteins_df",
    verbose=True,
    max_depth=1  # Depth is set to 1 since there's only one dataframe
)

# Display the tail of the generated feature matrix to verify the new features
print(feature_matrix.tail())

# Save the feature matrix to a new CSV file
feature_matrix.to_csv("proteins_feature_matrix.csv", index=True)  # Save with the index which is 'UniqueIndex'
