Widget not displayed on Windows 10 machine

austinMLB commented 6 years ago

Summary

After running the "view" command in the "2D ITK Images" example, the expected widget is not displayed. No output is provided as a result of that block of code.

Description

I am unable to get itkwidgets’ “view” to display anything on my Windows machine. The code seems to work OK on my Mac system. I'm using the “2D ITK Images” example from the itkwidget documentation. (Note that, from that example, the first “pip” command of the script doesn’t work on my Windows machine, but itk-io is installed, so I believe that is ok.)

After executing the “view(image)” image nothing displays.

In case this is helpful, if I downgrade itkwidgets to 0.7.0, the error goes away. Of the versions I tried, 0.7.0 was the newest release which did not exhibit the problem.

@austinMLB Thanks for the detailed report! What browser and browser version are you using on Windows?

austinMLB commented 6 years ago

@thewtex, It was an Edge browser. My browser is currently at "Microsoft Edge 41.16299.248.0", but I can't say for sure what version I had when I was trying this. If no one else is seeing the problem, I'll try look a little more deeply at my setup.

I re-tested this in the same anaconda environment I had used before, and everything seemed to work with the 0.10.2 version of itkwidgets. My best guess would be that some Windows and/or Edge update , in the past few weeks, resolved the issue. Regardless, I seem to be getting the correct behavior now. Thanks.
