python - Trying to create scatter matrix (feature pair plot in seaborn) but Truth Value Ambiguous error

Question

I am trying to create feature pair plot in seaborn. But I keep getting error:

"The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all()."

This is complete code:

    sns.pairplot(X_train,hue= y_train, diag_kind='hist'); # we want histograms along the diagonals

X_train dataframe consists of 4 columns: mass, height, width, color_score

y_train dataframe consists only of column: fruit_label (values: 1,2,3,4) 

When I try to use "hue= y_train.values", error being displayed changes to " Index data must be 1-dimensional"

Can someone please explain what is happening?
