Resolving Python Package Installation Error: [SSL: TLSV1_ALERT_PROTOCOL_VERSION]

When attempting to install a Python library using pip, you may encounter an SSL error: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version. This error arises due to recent TLS deprecation for pip.

Solution:

To resolve this issue, upgrade pip to the latest version:

curl https://bootstrap.pypa.io/get-pip.py | python

Note: If you are using pip within a virtual environment, you need to upgrade pip within that environment.

Step-by-Step for PyCharm (virtualenv) Users:

1. Run the virtual environment shell.

2. Execute the pip upgrade command:

   curl https://bootstrap.pypa.io/get-pip.py | python
