The conflict is caused by:
    The user requested sphinxcontrib-mermaid>=1.0.0
    The user requested (constraint) sphinxcontrib-mermaid==2.0.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip to attempt to solve the dependency conflict
