问题 I'm attempting to connect a datatable with a multiselect widget in bokeh. I've searched around and gathered that I need to develop a function to update the data source for the data table, but I seem to have two problems. I cannot seem to access the value of the multiselect object after I click it. I cannot seem to push the change to the notebook after receiving the change. Here's an example of my code: import pandas as pd from bokeh.io import push_notebook from bokeh.plotting import show,

问题 In my notebook I've a loop in which I want to ask the user to binary "Yes" or "No". On this choice the algorithm is suppposed to continue. for i in range(n_total): display.clear_output(wait=True) waiting_for_scoring = True print("True or False?") display.display(widgets.HBox((true_button, false_button))) a = true_button.on_click(on_true_button) a = false_button.on_click(on_false_button) while waiting_for_scoring == True: #waiting for user input pass How can I make the loop to wait, after the

问题 When trying to load Cython extension from my Jupiter notebook %load_ext Cython I get the below message: The Cython module is not an IPython extension I did not have this problem a couple of weeks ago, when I wrote a Cython extension on my nb. I have tried to upgrade ipython and cython both from my regular environment (I am using a Mac running 10.11) and from Anaconda, with no success. Any tips? Thanks a lot! 回答1: Cython is not an IPython extension, so %load_ext won't work on it. You can still

问题 I have recently upgraded the Graph Lab create version that I had. While running codes using the Jupyter console I came up with the following errors: from __future__ import division import graphlab import math import string **Error: ACTION REQUIRED: Dependencies libstdc++-6.dll and libgcc_s_seh-1.dll not found. 1.

问题 I've got this table: A DataFrame table which is made by using Jupyter Notebook. This is actually only part of the table. The complete table is actually a .csv file, and by using .head() function, only the first five rows are shown. I need to write a function that returns and prints the maximum value, out of all the values in the second column, which its label is 'Gold'. That function should return a single string value. I looked up at several sources before writing my question, trying many

问题 I am attempting to track progress in the following code: from toolz import compose calculator = compose(my_function, list, my_dict.get, tuple) result = list(zip(*map(calculator, my_values))) my_values is a list of length ~1mio. My first attempt is to add a counter to my_function that increments and print it out when a multiple of X (e.g. X==500 ) is reached. Is there a pythonic or cleaner way to achieve this, i.e. without adding lots of counters to various loops? A progress bar in jupyter

问题 I have a data set that consists of 1440 rows × 297 columns . I tried to plot 03_jan_2018 in terms of Time(X-Axis) and Density (Y-Axis), but I'm faced with a problem. The outcome graph is not enough clear and also the X-Axis is not appeared!! I would like to make something like this: But I'm ending up with this: Can anyone help me? Thanks in advance! 回答1: An easy fix for this is to increase the figure size. plt.figure(figsize=(80,40)) plt.plot(data.hour_formatted, data['03_jan_18']) plt.show()

问题 I used to be able to change the default start up folder for Jupyter (the folder Jupyter displays in browser when it was first started) by modifying the "start in" option of the Notebook launch icon's properties on Windows, as described here and here. However, this is not working any more after I recently installed Anaconda 3. Even though I changed the "start in" folder to the folder I wish, the browser still goes to "Documents" folder by default. I tried doing this as admin, still didn't work

问题 I had been trying to make with some interactive plot using Altair on jupyter lab. I had reached this stage where the results is below. As you can see, the line doesnt pop to the front when its highlighted. How do I make it pop to the front? Attached is the code. import altair as alt source = df selection = alt.selection_multi(fields=['class'], on='click') color = alt.condition(selection, alt.Color('class:O', legend=None, scale=alt.Scale(scheme='category10')), alt.value('lightgray')) base =
