问题 How do you update jupyterlab using conda or pip? I understand that conda update jupyter updates jupyter notebook (I have Anaconda), but I'm not sure this takes care of jupyterlab as well. 回答1: conda update jupyter will not automatically update jupyterlab.

问题 It appears that somehow one of my kernels is deleted. And perhaps that's why I am getting this error. How could I possibly fix it? Can I reinstall something (the kernel in the base environment perhaps)? If no better option is available, I would try reinstalling anaconda altogether as a last resort according to: Default kernel in jupyter notebook (Python3) not working. I have tried using the following: Installation of Jupyter Lab: requirements already satisfied Kernels don't show up when

问题 Is it possible for a jupyter notebook to get the name of its own file, similarly to what we would do from a python script? os.path.basename(__file__) doesn't seem to work, at least for me on jupyterlab sys.argv[0] returns my_home/anaconda3/lib/python3.6/site-packages/ipykernel_launcher.py 回答1: The only way I've found is through JavaScritp as in this answer. The compact form is a cell like this: %%javascript IPython.notebook.kernel.execute(`notebookName = '${window.document.getElementById(

问题 I'm implementing widgets in my jupyter notebook (via anaconda). I tried first by using an old code from a professor of mine, but it's not displaying widgets. I tried installing: jupyter labextension install @jupyter-widgets/jupyterlab-manager But it was unsuccessful This was presented when I attempted installation of the package via windows command prompt: C:\Users\davio>jupyter labextension install @jupyter-widgets/jupyterlab-manager Traceback (most recent call last): File "C:\Users\davio

问题 I want to number the LaTeX equation, I searched internet that I shall use %%javascript MathJax.Hub.Config({ TeX:{equationNumbers:{autoNumber:'all'}} }); I tested with an equation also with \eqref{} : In equation $\eqref{eq:sample}$, we find the value of an interesting integral: \begin{equation} \int_0^\infty \frac{x^3}{e^x-1}\,dx = \frac{\pi^4}{15} \label{eq:sample}{\tag{99}} \end{equation} The output in JupyterLab is So far everything looks alright, however I start any another cell, use
