<p dir="auto">Changes are coming to pip, Python's package installation tool, in October 2020. Please read and share this migration guide: <a href="https://pip.pypa.io/en/latest/user_guide/#changes-to-the-pip-dependency-resolver-in-20-2-2020" style="color:#3983C4">https://pip.pypa.io/en/latest/user_guide/#changes-to-the-pip-dependency-resolver-in-20-2-2020</a> .</p>
<p dir="auto">We're working on improving the Python packaging toolchain, foundational work that will (in the long run) make the whole Python package installation experience way less confusing.</p>
<p dir="auto">The pip team made a 2-minute video to explain what's up:</p>
