Unable to run PCA from Orange GUI

I am unable to find the PCA module in Orange. From the documentation it seems to be present but I cannot find it in the GUI.

I have installed all the addons and I can find PCA in the Orange Python library orngPCA.

My Orange version is installed through pip and is 2.7.2.

Solution

  • I had such problem before. I also had installed orange with pip. It seems orange is very sensitive to the version of the packages it depends on. What I did to make it work was the following (in Windows 7):

    1. Uninstall Orange
    2. Download the Orange with Python installer
    3. Open the downloaded file with 7zip
    4. Within 7zip, open the folder "$COMMON_DESKTOPDIRECTORY"
    5. There you'll see the package installers. Install, in this order, setuptools, then pyqt, then pyqwt. You probably want to uninstall these through pip before overwriting.
    6. Install Orange through the installer.

    I know it's ugly, but it was the only way I could make it work without having to uninstall my existing Python installation.
