Python typeerror: unhashable type: 'slice' for encoding categorical data

I am getting

TypeError: unhashable type: 'slice'

when executing the below code for encoding categorical data in Python. Can anyone please help?

# Importing the libraries

import numpy as np

import matplotlib.pyplot as plt

import pandas as pd

# Importing the dataset

dataset = pd.read_csv('50_Startups.csv')

y=dataset.iloc[:, 4]

X=dataset.iloc[:, 0:4]

# Encoding categorical data

from sklearn.preprocessing import LabelEncoder, OneHotEncoder labelencoder_X = LabelEncoder()

X[:, 3] = labelencoder_X.fit_transform(X[:, 3])

To get rid of unshakable tye slice error you should use Values either while creating variable X or while encoding as mentioned above:-

import numpy as np 

import matplotlib.pyplot as plt 

import pandas as pd 

dataset = pd.read_csv('50_Startups.csv') 

dataset = pd.DataFrame(np.random.rand(10, 10)) 

y=dataset.iloc[:, 4].values X=dataset.iloc[:, 0:4].value
