I have created my virtual environment by running "python -m venv myenv" in the terminal and then activated it using "myenv/scripts/activate". Then I installed all the necessary libraries which are given in requirements.txt file by running "install -r requirements.txt" on terminal . Then the last step was to change the directory by running "cd chatbot" on terminal and then running "streamlit run ollama.py" on terminal. And we get our chatbot.
