Hi,

I was at the PyCon 2013 talk (I asked about my camera not working on a Retina MacBook Pro).

I wanted to let you know that I was able to get my camera working out of the box with Ubuntu 12.10 in VMWare (I haven't tried VirtualBox yet, but I suspect it will work).

It was relatively easy to get all of the other bits installed and working too, so I thought I'd share. It might be a better distro to use for future demos?

Here's the (hopefully correct) set of packages I had to install:

  • sudo apt-get install python-opencv
  • sudo apt-get install python-setuptools
  • sudo easy_install pip
  • sudo pip install github.com/ingenuitas/SimpleCV/zipball/master
  • sudo apt-get install python-pygame
  • sudo apt-get install python-numpy
  • sudo apt-get install python-scipy
  • sudo apt-get install python-ipython
  • sudo apt-get install ipython-notebook

And then I used the provided instructions for running the notebook:

simplecv notebook --pylab inline

Hmmm

I did a clean install of Ubuntu on Virtualbox, but I'm seeing the same kind of artifacting I was seeing with the demo setup.

I'm thinking that either Virtualbox has some sort of issues with the camera, or there was some update that may have been installed at some point in my VMWare Ubuntu install that I don't have with a clean install.

I'll poke at this some more and present my findings.

Yes, Ubuntu 12.10 with VMWare (64-bit).

Ubuntu 12.10 with Virtualbox doesn't appear to be working with my camera... yet. I'm working on figuring out why.

Just to be clear, you got this working on a VM of 12.10 right? That sounds like it should be about the right set of required packages. The only glaring omissions would be sklearn and orange. We keep most of the installation instructions on the main github page. My guess is that your particular issue probably lives more in the VM space that it does in the installation space. I know there are some VM patches that should allow for USB support.

I've been trying to follow the machine learning demo from Pycon on my shiny new Raspberry PI, (doing a "Is the cat looking out my window detector") and it's been a little frustrating. There's a select timeout issue with the camera (which could very well be the camera, it's a cheapo one). And then there's orange.

Orange is big, and a pain to compile on the pi. After letting it go for hours overnight, it wound up failing, I'm not clear if it was a memory thing or if there was something more fundamental wrong.

Any idea if there's a binary package for it somewhere, or am I going to have to setup a cross compile environment for that?
