jupyter-notebook

问题 I don't want to write the same function in each Jupyter Notebook files. It would be easier if I just need to edit the function once without the need to edit in each .ipynb file. The problem is, I have to restart kernel if I edit the .py file which will re-start everything. Is there any way I can simply call a function from several .pynb files? PS: After I have edited the .py, it does not affect the .ipynb file. 回答1: Yes, you need a make .py file with function defined and import that file then

问题 I tried to follow this doc to launch jupyter in my Mac, but it did not work. Could anyone help?

问题 Important to know: I am working on jupyter notebook. I want to create a logger to which I will redirect the STDOUT and STDERR but I also want to see those outputs on the jupyter notebook output console. So far what I have implemented is: import logging import sys class StreamToLogger(object): """ Fake file-like stream object that redirects writes to a logger instance. """ def __init__(self, logger, log_level=logging.INFO): self.logger = logger self.log_level = log_level self.linebuf = '' def

问题 I'm writing python using jupyter notebook and I have two cells that can influence each other. I'm wondering is it possible to leave some certain cells out after I click Restart & Run All so that I can test the two cells independently? 回答1: One option based on Davide Fiocco's answer of this post and that I just tested is to include %%script magic command on each cell you don't want to execute. For example %%script false --no-raise-error for i in range(100000000000000): print(i) 回答2: If you put

问题 I am not sure what happened but I am no longer able to run my Jupyter notebooks. I am getting the following error Traceback (most recent call last): File "C:\Users\asher\Anaconda3\lib\site-packages\tornado\web.py", line 1699, in _execute result = await result File "C:\Users\asher\Anaconda3\lib\site-packages\tornado\gen.py", line 742, in run yielded = self.gen.throw(*exc_info) # type: ignore File "C:\Users\asher\Anaconda3\lib\site-packages\notebook\services\sessions\handlers.py", line 72, in

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

问题 I come here because I have an issue with my Jupiter's Python3 notebook. I need to create a function that uses the multiprocessing library. Before to implement it, I make some tests. I found a looooot of different examples but the issue is everytime the same : my code is executed but nothing happens in the notebook's interface : The code i try to run on jupyter is this one : import os from multiprocessing import Process, current_process def doubler(number): """ A doubling function that can be

问题 I'm trying to get a progress bar going in Jupyter notebooks. This is a new computer and what I normally do doesn't seem to work: from tqdm import tqdm_notebook example_iter = [1,2,3,4,5] for rec in tqdm_notebook(example_iter): time.sleep(.1) Produces the following text output and doesn't show any progress bar HBox(children=(IntProgress(value=0, max=5), HTML(value=''))) Similarly, this code: from ipywidgets import FloatProgress from IPython.display import display f = FloatProgress(min=0, max=1
