<p>Hi Aron and Sebastien,<br>
</p>
<p><br>
</p>
<p>Thanks for your helpful comments. As you expected, VTK 8.1.0 can support python 3. Up to now, I almost finished except some errors in the client (see the figure). I guess js also need to upgrade, right? Hope some vtk-only examples can be obtained in the
future. Thanks again.<br>
</p>
<p><br>
</p>
<p>Regards,<br>

<div dir="ltr">The older Autobahn had a number of issues with Python 3 - so I would expect you to have problems. We were able to make it work with python 3 by backporting a number of python3 fixes, but can you upgrade to VTK 8.1.0? Then you can use the newest
autobahn and twisted, with wslink.
<div><br>
</div>
<div>launcher.py has migrated to wslink: <a href="https://github.com/Kitware/wslink/blob/master/python/src/wslink/launcher.py" target="_blank">https://github.com/<wbr>Kitware/wslink/blob/master/<wbr>python/src/wslink/launcher.py</a></div>
<div>but it didn't change very much. </div>
<div><br>
</div>
<div>I don't know if we have a vtk-only example of migration, but the Visualizer app migrated, including the launcher, I believe.</div>

<p>Hi all,<br>
</p>
<p><br>
</p>
<p>I referred vtkweb/launcher.py in VTK 8.0.0 to write my own codes with twisted 17.1.0 and autobahn 0.8.14, it can work using python 2.7. But when I upgraded python to 3.4, it did not respond to http request, and in front-end displayed "404 No such Resource".
So I wonder if launcher.py can support python 3.x? Need to modify something? Any suggestions are welcome. <br>
</p>
<p><br>
</p>
<p>BTW, I noticed that launcher.py has been removed <span style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:16px; background-color:rgb(255,255,255)">in VTK 8.1.0</span>. Does that mean VTK web application use a new architecture?<br>
</p>
