# Set the working directory inside the container
WORKDIR /app

# Upgrade pip to ensure we are using the latest version

# Install the Python dependencies from requirements.txt
# And add a verification step to ensure streamlit is installed correctly.
# The build will fail here if streamlit is not found.
