The kernel appears to have died

Question

I have ran into Kernel Restarting problem after running this code, and have no idea what could be wrong:

df.columns = df.columns.str.replace(' ', '_')

df.fillna(value = {'Unnamed:12': 0, 
                   'Unnamed:13': 0,
                   'Unnamed:14': 0}, inplace = True)

# X[:, 1:3] = imputer.transform(X[:, 1:3])
X = df.iloc[:, 1:12].values
y = df.iloc[:, 1].values

#encoding categorical data into dummy

#encoding independante var
labelencoder_X = LabelEncoder()
X[:, 10] = labelencoder_X.fit_transform(X[:, 10]) #dummy quantity
onehotencoder = OneHotEncoder(categorical_features = [10])
X = onehotencoder.fit_transform(X).toarray()
#etc for each dummy

#encoding dependant var
labelencoder_y = LabelEncoder()
y = labelencoder_y.fit_transform(y)

and i get window with this error message:

Kernel Restarting
The kernel appears to have died. It will restart automatically.

I saw another similar problem and try solution from it:

Jupyter | The kernel appears to have died. It will restart automatically |.

conda update mkl - do not help
conda install numpy - do not help too
RAM usage 6.3/16 Gb

I also read this topics, but do not get solution:

What is strange i did the same transformation with another dataset and everything was just fine.
