OMG, I love the concept of Linux in its entirety but is times like this that I wonder are we going in the right direction. For e.g. I write "print 'hello world', I get sorry you need to use (). Okay, install something, then I get sorry you need this, then install that, then sorry you need this version because that version of that is this etc etc etc. In Windows you rarely see that and I am not a fan of Windows by far, why can't Linux devekopment catch up to that point where if you need something you can just install and be done with it, instead I find if I install e.g. not exact figures but the point I am making is, opencv then I find that I need a specific version for the python version and then a specific version of numpy and by the time I finish installing all the requirements I cannot do my project because the feature I want to implement is not supported by these versions that I have installed. I need to get the stars and moon aligned before something really works and most times I have to rely on others who have done it before otherwise I am done for.
