Package installation failure due to pyqt
When i am following the instruction and installing pandas packages listed in `requirement-dev.txt` on my new laptop, i get an error: `Could not find a version that satisfied the requirement pyqt (from -r requirement-dev.txt (line 48)). No matching distribution found for pyqt.`

And I need to change the package name to `pyqt5` to succeed the installation. Is it something that should also be changed in `requirement-dev` or it's due to issue of my virtualenv which i don't think it is though?
