One 、 The data contains missing values 、 Infinite problem

1.1 ValueError: Input contains NaN, infinity or a value too large for dtype(‘float64’).

1.2 solve

• The data contains missing values 、 Infinite equal . Use the following code to determine and locate which data has the problem

print(np.isinf(X_train).any()) # Judge X_train Is there an infinite number in 
print(np.isfinite(X_train).any()) # Judge X_train Whether or not is a finite number 
print(np.isnan(X_train).any()) # Judge X_train Contains missing values in
