Orange canvas does not work for visualise, classify, regress

A place to ask questions about methods in Orange and how they are used and other general support.

Orange canvas does not work for visualise, classify, regress

Postby mithua » Tue May 06, 2014 22:21

I am new to Orange data miner. I installed the full version in Python 2.7 yesterday in my desktop and laptop PC. In both, I have Windows 7 (64-bit). I also added the plug-ins.

The canvas is really beautiful.

However, I can load the data and do data management, but after that point - visualise, classification, regression, etc. won't work. E.g., in visualise, I cannot see any variable in x and y drop down menus. I have kept (for simplicity) just a class variable (numeric or nominal each time) in its location in the select attributes node, and a few other numeric variables as predictors.

Hi,

check your settings for propagation in each widget - ie propagate on change, or if it is manual. Each widget you can tell it how to propagate data. The next widget won't get the data until it is propagated. It can be a pain to get it to push data to the next widget but I've always been able to do it eventually.

I tried to find the settings, both under general settings, drop down menu/right click. However, nowhere I could locate propagation on change or manual. Could you help to locate, where this feature could be available, or if there's any button to execute or run the process flow, something ??

Hi,

ah the correct label is 'commit' or 'commit on change', i think there might be other variations as well. They will be located in each individual widget that you place on the canvas.

Here is an example widget (alas not many images that show the widgets that I could find)

Yes, I found some widgets with the 'commit' or 'commit on change' or 'send selection on ... <choices>' and other equivalents. They are all checked, but the problem persists. Just to add, all widgets are joined by arrows on the canvas, but only the data widgets work (loading, selection, display for example).

I presume that this problem could stem from some other issue that propagation. I installed Orange in the default way, and reinstalled to be sure in two different PCs, but the problem persists in both places. I had Python 2.7.6 installed before in both the PCs, but after reinstalling Python (with Orange data miner), I saw that the Python new version reinstalled has become 2.7.2. I'm wondering if some incompatibility could arise from the different versions or their is a bug version or something .... I checked in the control panel -> installed programmes that both versions were installed, Python 2.7.6 earlier and Python 2.7.2 on the day Orange was installed (later).

Strange. Can you provide an example workflow and data set?
Also can you please locate and post the Canvas log file. On Windows 7 this should (usually) be in 'C:\Users\UserName\AppData\Local\Orange Canvas\canvas.log'

The dataset is perfect, because it worked with several other software. It was a class of 4 categories (0, 1, 2, 3) and a two variables which are continuous >0.

An excerpt is:
Frequency Duration Expert4cat
7 0 0
3 0 0
11 5 1
11 2 1
5 0 0
8 0 0
9 6 1
4 4 1
3 0 0
9 1 0
24 14 1
31 53 2
24 16 2

I tried to attach the log file, but I couldn't. So I'm pasting it, which is a bit ugly !!

Re: Orange canvas does not work for visualise, classify, reg

You seem to be routing your data through the "Data Table" widget. Did you actually select any instances in that widget?
If you just mean to test the learners on all of the data then connect the output from the "Select attributes" to the "Test Learners" directly.

Indeed you're right ! Even before testing learners, I wanted to simply visualise and explore using visualise widgets. So upon connecting DIRECTLY with the select attributes widget it works perfectly ! Thanks very much and most importantly it'll help me get going on the beautiful Orange data miner !!
