问题 I'm trying to display a video from some arrays in an notebook in jupyter-lab. The arrays are produced at runtime. What method to display the images can deliver a (relatively) high framerate? Using matplotlib and imshow is a bit slow. The pictures are around 1.8 megapixel large. Above some very small example to visualize what I want to achieve. while(True): #should run at least 30 times per second array=get_image() #returns RGBA numpy array show_frame(array) #function I search for 回答1: The

问题 I'd like to edit the JupyterLab Dark Theme, so that axis labels on inline plots can be clearly read. Example of the problem: To remedy this problem I'd like to change the background colour of output cells which contain an image to a shade of grey. I used Chrome DevTools to insepect the webpage and found the class class="p-Widget jp-RenderedImage jp-mod-trusted jp-OutputArea-output" . I've noted that I can workaround this problem by using the JupyterLab Light Theme or by using a dark plotting

问题 I am running a Data8 instance of JupyterHub running JupyterLab on a server, and pd.read_clipboard() does not seem to work.
