Truth value of a Dataframe is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all()

I've tried to do pairplot by seaborn with my csv data (this link) by follow code according to seaborn site.

import numpy as np  import matplotlib.pyplot as plt  import seaborn as sns  import pandas as pd    freq_data = pd.read_csv('C:\\Users\\frequency.csv')    freq = sns.load_dataset(freq_data)  df = sns.pairplot(iris, hue="condition", height=2.5)  plt.show()  

the results show the trackback of ambiguous of dataframe

    Traceback (most recent call last):    File "\.vscode\test.py", line 8, in <module>      freq = sns.load_dataset(freq_data)    File "\site-packages\seaborn\utils.py", line 485, in load_dataset      if name not in get_dataset_names():    File "\site-packages\pandas\core\generic.py", line 1441, in __nonzero__         raise ValueError(  ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().  

I've checked my data and result it here

I have no ideas what happen with my dataframe :( Please advice me to solve these problem

Thank you everyone
