jupyter-lab

问题 I have Jupyter running in a tmux session on an ec2 instance. I have very long-running cells, but when I close my browser or laptop lid, the notebook no longer writes output cells (and may crash the python kernel). This is how I launch labs on my remote instance: jupyter lab --ip=0.0.0.0 --port=5002 --no-browser --allow-root I'm looking for a solution to run a notebook indefinitely without losing data and without having to keep my local computer on. I don't want to use a VNC or X-windows

问题 After attempting to update conda packages, I am no longer able to start either Jupyter Notebook or Jupyter Lab. Most conda commands also result in an error in terminal. While each command results in a slightly different error, every one terminates in the following statement: ImportError: dlopen(/Users/USERNAME/anaconda3/lib/python3.7/lib-dynload/_ctypes.cpython-37m-darwin.so, 2): Library not loaded: @rpath/libffi.6.dylib Referenced from: /Users/USERNAME/anaconda3/lib/python3.7/lib-dynload/

问题 In jupyter notebook , I can configure an automatic cell timing with nbextensions, the result is like so: How can i do this in jupyter lab ? I didn't found any extensions that did a similar thing. Obs.: I know that a similar result can be achieved with %%time magic, but i want it to be automatic, so I don't have to place the magic function at the begining of each cell 回答1: Requirement JupyterLab >= 2.0.2 Let's move step by step Extension availabel in jupyter lab is jupyterlab-execute-time

问题 After creating a FastText model using Gensim, I want to load it but am running into errors seemingly related to callbacks. The code used to create the model is TRAIN_EPOCHS = 30 WINDOW = 5 MIN_COUNT = 50 DIMS = 256 vocab_model = gensim.models.FastText(sentences=model_input, size=DIMS, window=WINDOW, iter=TRAIN_EPOCHS, workers=6, min_count=MIN_COUNT, callbacks=[EpochSaver("./ftchkpts/")]) vocab_model.save('ft_256_min_50_model_30eps') and the callback EpochSaver is defined as from gensim.models

问题 I would like to enable word wrap for the code cells in jupyterlab, but do not manage to find how. Already tried: File --> Settings --> Text Editor --> User Overrides: {"lineWrap": true} , which toggles the greyed-out "word wrap" in the "Editor" menu, but does not solve my problem This code also did not work (neither did simply "Cell": {...} ): "CodeCell": { "cm_config": { "lineWrapping": true } } 回答1: Try the following, { "codeCellConfig": { "lineWrap": "wordWrapColumn", "wordWrapColumn": 80

问题 Context: I started teaching myself a few new libraries using Jupyter Lab. I know showing emotion on SO is strictly forbidden and this will get edited, but WOW, Jupyter notebooks are cool! Anyway, I'm taking notes in markdown as I work through code examples. It gave me the idea of writing my own little textbook as I learn. For example, in notebook 1, I talk about (teach myself) linear regression. It take notes on vocabulary, show some mathy formulas then work through some code examples. End

问题 In Jupyter Notebook you can toggle the cell output by going into command mode and pressing "O". This command does not work on Jupyter Lab, and I don't see an option to add it. Is there a way to do this, even if it means writing the code for the command? 回答1: As Arkady said, this looks like a duplicate from this post. Note, you can also do this in the sidebar if you don't want to code it. 来源： https://stackoverflow.com/questions/57009598/is-there-a-way-to-toggle-cell-output-in-jupyter-lab
