The conflict is caused by:
    The user requested sphinx<5.0.0 and >=4.4.0
    The user requested (constraint) sphinx===4.4.0,===7.1.2

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
