Problems with Confusion matrix #1505
Comments
*Version 3.3.7 |
Can you share a minimum working example workflow? On 3.3.7 with below scheme, I can't reproduce. |
Even when the canvas is empty, I get an error. |
I don't have errors anymore. I don't know why . I started Orange again a minute ago and it works. 😄 |
Do you remember what scheme you had and what you did right before the problem started manifesting? |
@JelenaKitanovic Is there any chance to reproduce this bug? |
Hi,
Temporal fix I done to be able to continue working:
Hope this helps. Great job! |
Thanks, you've really nailed it. I guess #1523 should fix it. |
I cannot put Confusion matrix on canvas it shows error:
Could not create 'Confusion Matrix'
Traceback (most recent call last):

I used the Iris dataset, and yesterday everything worked properly. Today I can't use Confusion matrix at all.
Orange version 3.3
