A Complete Tutorial on Ridge and Lasso Regression in Python http://www.analyticsvidhya.com/blog/2016/01/complete-tutorial-ridge-lasso-r… In Step 2 "Why Penalize the Magnitude of Coefficients?" we are shown this code: #Importing libraries. The same will be used throughout the article. import numpy as np import pandas as pd import random import matplotlib.pyplot as plt %matplotlib inline I get an error on the last line. I am running this code in Idle Python 3.4.4 Shell...

AuckPUG's last (virtual) Coding Evening for 2022
by dn Nov. 30, 2022

Nov. 30, 2022

Wednesday 7 December, 1800 for 1830 NZDT/0530 UTC We will continue the "Crafting Software" series, gradually developing Monty's Python Supermarket. The evening's aim is to move the product-prices from their hard-coded dict[ionary] into a flat-file (introducing Python I/O), and then to do same with the Accountant's favorite tool - a Workbook or Spreadsheet (Python's library to interact with LibreOffice-Calc and MS-Excel). You can treat it as a code-along-at-home exercise or just watch the fun. The Web-conference URL and a QuickStart Guide (for those who didn't attend last time) will be provided upon RSVP. All welcome! https://www.meetup.com/nzpug-auckland/events/hgxmwsydcqbkb/ The Smart Iterators Challenge has finished (after five Challenge-weeks). Congratulations to all who participated (and if you didn't have time to complete, you're welcome to continue at your own pace). Particular pride for those who hung-in-there right to the end, making astute discoveries and learning ideas which have already been adopted into professional-practice. Well done! A "Retrospective, Review, and Reflection Wrap-up" document is available to participants/upon request. Advice and assistance will continue to be available - please email off-list. -- Regards, =dn

python: setup.py: how NOT to install C extensions used only by tests
by Bartosz Golaszewski Nov. 30, 2022

Nov. 30, 2022

I have a module that has a tests/ directory which contains a C extension that's only used by test cases. I don't want to install it. I'm building it as a setuptools.Extension() added to setup() using the ext_modules argument. The test directory is not added to setup's packages argument. Even though none of the python sources from the tests/ directory gets installed when running setup.py install, the extension binary (and nothing else) is installed into site-packages/tests/. How can I prohibit setuptools from doing it? Best Regards, Bartosz Golaszewski

pip issue
by Gisle Vanem Nov. 30, 2022

Nov. 30, 2022

Hello list. I have an issue with 'pip v. 22.3.1'. On any 'pip install' command I get warning like this: c:\> pip3 install asciinema WARNING: Ignoring invalid distribution -arkupsafe (f:\gv\python310\lib\site-packages) WARNING: Ignoring invalid distribution -arkupsafe (f:\gv\python310\lib\site-packages) Collecting asciinema Downloading asciinema-2.2.0-py3-none-any.whl (92 kB) ... Otherwise no issues. But where is this text "-arkupsafe" stored and how to get rid it it? I've searched through all of my .pth files and found no such string. I assume this is an entry for an orphaned package "MarkupSafe" since a 'pip list | grep markup' will list 'MarkupSafe 2.1.1'. -- --gv

But between certain intervals > of a few seconds I am getting the latitude and longitude data ( its > printing GPS data not found ?? ) in the python console. I would guess the 8 seconds in timeout = time.time() + 8 is too short. Most GPS receivers repeat a sequence on NMEA sentences and the code is specifically looking for $GPGGA. Add print(buff) to see the sentences being received. I use the $GPRMC since I'm interested in the position, speed, and heading. It's a different format but if you only want lat/lon you could decode it in a similar fashion as the $GPGGA.

Stefan Thank you. I should have said this has been working fine for years and years until Ubuntu 2022.04 on a new droplet running Apache/2.4.52 I will refactor it one day - especially if the script is implicated. But I think I have to learn how to use lsof first!
