hello harshit

i am getting the following error:

D:\Twitter-Sentiment-Analysis-master\venv\Scripts\python.exe D:/Twitter-Sentiment-Analysis-master/trainSentiment.py
Traceback (most recent call last):
File "D:/Twitter-Sentiment-Analysis-master/trainSentiment.py", line 34, in
allFeaturesList = getAllFeaturesList()
File "D:\Twitter-Sentiment-Analysis-master\commonUtils.py", line 92, in getAllFeaturesList
allFeaturesList = pickle.load(open(FeaturesListPkl,'rb'))
UnicodeDecodeError: 'ascii' codec can't decode byte 0x8e in position 5: ordinal not in range(128)

i changed 'rb' to 'r' in the following line.
allFeaturesList = pickle.load(open(FeaturesListPkl,'rb'))

error:
Traceback (most recent call last):
File "D:/Twitter-Sentiment-Analysis-master/trainSentiment.py", line 34, in
allFeaturesList = getAllFeaturesList()
File "D:\Twitter-Sentiment-Analysis-master\commonUtils.py", line 92, in getAllFeaturesList
allFeaturesList = pickle.load(open(FeaturesListPkl,'r'))
TypeError: a bytes-like object is required, not 'str'
