After some messing around, I figured out that when pyqt 4.11.4 is installed, Spyder is unable to start, and crashes at the splash screen (Windows states that \"python.exe\" is not responding). Downgrading back to pyqt 4.10.4 resolved the issue.\r\n\r\nI tested this condition in a new conda environment with only Python 3.4.4, Scipy 0.16, Spyder 2.3.8, and all dependencies for those three packages.
