How to get active kernel name in Jupyter notebook

由 女生的网名这么多〃 提交于 2019-12-07 17:35:15
问题 I would like to make a notebook that prints the active kernel name. I registered multiple venvs as kernels using the python -m ipykernel install --user --name <kernel_name> In the notebook I would like to print some metadata about the active kernel. How can one get the name of the active kernel? EDIT: Here are the particular versions in my stack ipykernel==4.5.2 ipython==5.3.0 jupyter==1.0.0 nevertheless, the question should be answered in general. 回答1: One way to do this is using Javascript

Launch Dash from Jupyter Notebook

由 纵饮孤独 提交于 2019-12-07 17:02:29
Is there a way I can launch a Dash dahsboard using the below line of code in Jupyter notebook? # if __name__ == '__main__': # app.run_server(debug=True) When I try to launch this I get an error. The only way to correct it is to set debug to false. But then the Dashboard does not update automatically when the data feeding the charts is altered. EDIT I just found out that a valuable GitHub user published the following library . This is the direct link to the respective repo . See his documentation and examples to implement it successfully within jupyter. It worked for me. DON'T understimate this

How to enable timing magics for every cell in Jupyter notebook?

由 梦想与她 提交于 2019-12-07 10:31:35
问题 The %%time and %%timeit magics enable timing of a single cell in a Jupyter or iPython notebook. Is there similar functionality to turn timing on and off for every cell in a Jupyter notebook? This question is related but does not have an answer to the more general question posed of enabling a given magic automatically in every cell. 回答1: A hacky way to do this is via a custom.js file (usually placed in ~/.jupyter/custom/custom.js ) The example of how to create buttons for the toolbar is
