Hello, i tried to install the matlab lib on the virtuel environment builder. And it worked the inveronment successfully installed the matplotlib. I added the matplotlib in the requirements.txt and setup.py     here is the open archive of the virtuel core snap. And on the virtuel control no error occurs. Besides that when i build the arm64 snap for the real control, i always get the error page. To mention i also changed in the datalayer.py the return value to the control ones used. Afterwards i build the snap without errors.     thank you for your service and quick replys. best regards UDK_developer ... View more

Hello,  i tried out the python example of the python-webserver  and well if you see it works correclty. I can write values in the data layer. So when i looked in the mark down file there is a picture with the stylesheet.css but in my case he doesn't want to link the css file included in /www/stylesheet.css. i looked further in the code and copied the html file in a notepad. Then i created a file folder to my desktop i linked the stylsheet to the notepad data like this: When i execute the html file in notepad it puts following results:  I also changed some default values in the stylesheet.css to see if the linking is correct.  So when i build the snap for the ctrlx Core Device I only get the first picture without the stylsheet.css linking.  I got the python example webserver+datalayer from the sdk vers. 1.14.3.  best regards  UDK_developer       ...
