Can not install chatterbot in Anaconda

Question

While installing chatterbot in Anaconda using Python 3.7 I am getting the following error:

Found existing installation: PyYAML 3.13 Cannot uninstall 'PyYAML'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

Answer 1

Installing chatterbot in conda environment using Python 3.7

• Create new conda environment with Python 3.7

conda create --name chatterbot_example python=3.7

• Activate the environment:

source activate chatterbot_example

• Install chatterbot and chatterbot-corpus inside the environment:

pip install chatterbot
pip install chatterbot-corpus

• Create a basic shown in Chatterbot Documentation (example.py):

from chatterbot import ChatBot
from chatterbot.trainers import ChatterBotCorpusTrainer

chatbot = ChatBot('Ron Obvious')

# Create a new trainer for the chatbot
trainer = ChatterBotCorpusTrainer(chatbot)

# Train the chatbot based on the english corpus
trainer.train("chatterbot.corpus.english")

# Get a response to an input statement
print(chatbot.get_response("Hello, how are you today?"))

• Run the program:

python example.py

Output:
