kandi X-RAY | xfilter Summary
Simple wrapping for scipy's Butterworth filter and scipy.filtfilt. Works with gappy datasets by filling in values with a constant, filtering and then NaNing out gaps. Automatically determines length of regions with edge effects by estimating the filter's impulse response length and NaNs those out. Takes input frequency in dimensional units (time only): for e.g. freq=1/10, cycles_per="D" for filtering at the 10-day period. Another experimental aspect is that it attempts to filter along chunked dimensions using map_overlap. Because filters are "local" --- influence of a point is restricted to the impulse response length (approximately!) --- chunks that are large enough can be filtered independently of other chunks. xfilter uses dask's map_overlap to apply a filter such that edge effects are taken care of. This is currently working approximately. This software is alpha quality.

QUESTION
I'm trying to create a function, it exists and does not exist in the search feature. Condition does not exist, will display Error 404. Condition, exists. Then it will display from search. But in the code I wrote, it only shows Error 404.
This is my model:

QUESTION
I am trying to plot a line graph of some quantity, in this case, "bananas", vs Time using D3 and crossfilter. The dimension aspect of the plot does not seem to reflect the dimension values that I am inputting, though is possible that this is a conceptual issue with crossfilter, as I am new to using it. below is the script that I am using and the output plot, as you can see the y-axis runs 0-6 and there are 11 unique inputs for banana and time. Other examples that I have looked at for this type of plot appear to plot the equivalent to the quantity aspect of bananas (which runs from 8 to 668 in this case), so I was hoping for some clarity on what exactly is on my Y-axis and how to re-write my code such that it is actually plotting the number of bananas consumed as a function of time.

Answered 2021-Jun-01 at 12:23Thanks for including a complete working example with your question.
That looks like a plot of counts by time. If you want to sum the bananas, you could use

QUESTION
I am using Electron-builder to package my app.
Version: 22.4.0
Target: nsis
Adding a custom grpc client addon written in C++ is crashing the packaged app. After I run yarn dist and I install the app using the resultant setup exe, I try and start the app. But the screen goes white (i.e., it loads nothing) and after 5 seconds or so, the app crashes. If I start the app from node using yarn/npm start, it works properly, so I do not think that the problem is with the addon itself, probably my settings in package.json; since that's what has caused me the most pain till now.
My package json file:
...ANSWER
Answered 2020-Mar-27 at 07:21It was a permissions issue.
See #4818.
Figured out what the issue was. Because of "perMachine": true and "allowElevation": true, the program was getting installed into C:\ProgramFiles as an elevated user. But when I run it, it runs as a lower level user who doesn't have permission to write to the folder.
Can be fixed by only installing for the current user (i.e. "perMachine": false)

Install xfilter
You can use xfilter like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
