This is a duplicate, but my original issue is back. Sometimes the script node executes okay the first time after I start KNIME, but it always fails the next time I run it. It’s a simple script, and executes fine in the Configure window:
indat = input_table.copy()
import numpy as np
import pandas as pd
import pandas_profiling as pro
def get_var_category(series):
unique_count = series.nunique(dropna=False)
total_count = len(series)
if pd.api.types.is_numeric_dtype(series):
return 'Numerical'
elif pd.api.types.is_datetime64_dtype(series):
return 'Date'
elif unique_count==total_count:
return 'Text (Unique)'
else:
return 'Text'
def print_categories(df):
for column_name in df.columns:
print(column_name, ": ", get_var_category(df[column_name]))
def get_mode(series):
y = series.mode()
if isinstance(y, pd.DataFrame):
y = y.iloc[0, 0]
return y
dat = pd.DataFrame(indat.dtypes)
dat.reset_index(inplace = True)
dat = pd.concat([dat, pd.Series([get_var_category(indat[column_name]) for column_name in indat.columns])], axis = 1)
dat = pd.concat([dat, pd.Series([pd.isna(indat[column_name]).sum() for column_name in indat.columns])], axis = 1)
dat = pd.concat([dat, pd.Series([len(indat[column_name]) - indat[column_name].count() for column_name in indat.columns])], axis = 1)
dat.columns = ['col_name', 'dtype', 'data_type', 'NA', 'missing']
output_table = dat
The trouble seems to start with “OSError: [WinError 10038]”, and the memory error happens soon after:
