问题 I use cyrillic symbols in my Jupyter notebooks. In NoteBook №1 I run NoteBook №2. %run ./NB2.ipynb In NoteBook №2 I write in some txt file. TestText = open('C:\\TRASH\\test_text.txt', 'w') a = 'Иридий' #Iridium TestText.write(a+'\n') TestText.close() And when NB1 starts I get UnicodeDecodeError. ...can't decode byte 0x98 Full output is there: http://collabedit.com/tcev6 Briefly, Nbformat library call core.reads which, in its turn, read NB2 in win-1251 encoding. That's why first 'И' is the

问题 I am working with Python 3.6.1 on Jupyter 5. My goal is to test how portalocker manage concurrent appending on the same file. To accomplish that I have made a simple function that appends a single line to the same file and I use multiprocessing.Pool and Pool.map() to run the function in parallel. Here is the code in Jupyter notebook. cell 1 from time import time from multiprocessing import Pool import portalocker def f(*args): while time() < start + 1: pass with open('portalocker_test.txt',

问题 I use Jupyter Notebooks to implement and document changes that apply to our production databases. I program in Python and submit typical SQL statements to the server to fetch results and make changes. I like to print the sql as part of the cell output for verbose log of the change. I wanted pygments to help colorize the output so that the SQL would look as nice as possible. Seems that pygments uses css and I don't know how to get it included from pygments import highlight from pygments.lexers

问题 How do I add a local image to an IJulia notebook? The image is in the same local network folder as the IPYNB file. The folder is accessed via a symbolic link. I've tried both relative and absolute file names. <img src="test.png" alt="Image Test" style="width:600px">  Both show up the same, as a broken image link with "Image Test" next to the symbol.

问题 I've been using jupyter notebooks for the past couple of months with no issue, but suddenly when launching jupyter notebook through the Command Prompt (I'm a Windows 10 user) and try to create a new python3 notebook through the browser, I suddenly receive the following error: Permission Denied Error When Creating New Python Notebook Anyone know what to do? I've tried uninstalling and reinstalling Anaconda3 . I saw another post which suggested using export XDG_RUNTIME_DIR="" but export wasn't

问题 I am setting up my recurrent neural network in Azure: model = Sequential() model.add(GRU(units=512, return_sequences=True, input_shape=(None, x1,))) model.add(Dense(y1, activation='sigmoid')) But I am getting the error: TypeError: while_loop() got an unexpected keyword argument 'maximum_iterations' I am not cretin but I believe I may be doing something that is now depreciated in current versions of TensorFlow & Keras, as in this example a similar error has occurred and such errors were

问题 How do I enable vertical scrolling in a code block in a jupyter notebook? I've done it accidentally before, but now I can't reproduce it. What I found was set autoscroll = true in the file itself using a text editor... However, I did that... and it already has a setting, "scrolled": true . In the notebook, it has only horizontal scrolling, so I guess that is what the "scrolled" setting modified. 回答1: In order to enable vertical scrolling in an output cell of the notebook, you just need to

问题 This question already has answers here : Show grayscale OpenCV image with matplotlib (1 answer) plt.imshow shows color images for grayscale images in IPython (1 answer) Closed last year . I am doing my first steps using OpenCV (version 3.3.0 from opencv-python package on Mac OS). Using OpenCV inside jupyter notebook and displaying a greyscale image through matplotlib results in a greenish image instead of a greyscale one. %matplotlib inline import cv2 as cv import numpy as np import

问题 Hi I can t figure out how to properly use pyplot for multiple plots, in addition to the plot it also print me the full array of data # import numpy as np import matplotlib.mlab as mlab import matplotlib.pyplot as plt mu, sigma = 100, 15 x = mu + sigma*np.random.randn(10000) fig, axes=plt.subplots(nrows=4, ncols=2) # the histogram of the data axes[1,0].hist(x, 50) # kinda work, the problem is it print the array and then do the plot plt.hist(x, 50, ax=axes[0,0]) # not wokring inner() got

问题 I would like to use Jupyter Notebook for editing JModelica python scripts; however after installing, the Jupyter notebook cannot locate key libraries, such as pymodelica. Here is the process I followed to install Jupyter Notebook for JModelica Version 2.1: In the IPython terminal: !pip install jupyter In windows CMD I navigate using cd C:\JModelica.org-2.1\Python27\Scripts I then open using jupyter notebook Within the notebook I create a Python 2 file and attempt to import the pymodelica
