{{Warningbox|If you are installing 64-bit Python rather than 32-bit, and the ChipWhisperer software's graph widget's axis disappear, the fix is this: ''pip uninstall pyside'' and then ''pip install https://download.qt.io/official_releases/pyside/PySide-1.2.2-cp27-none-win_amd64.whl''. This uninstalls the current pyside package and installs the official QT Pyside package.}}

{{Warningbox|You may need to add ''--trusted-host pypi.python.org'' to the ''pip install'' command to allow HTTP connections. This is done as follows for example: ''sudo pip install --trusted-host pypi.python.org pyusb''}}
