pip is a package-management system used to install and manage software packages written in Python. Many packages can be found in the default source for packages and their dependencies — Python Package Index (PyPI).[4]


Python 2.7.9 and later (on the python2 series), and Python 3.4 and later include pip (pip3 for Python 3) by default.[5]


pip is a recursive acronym for "Pip Installs Packages".[6]

Command-line interface[edit]




An output of pip install virtualenv


Most distributions of Python come with pip preinstalled. If pip is missing, it can be installed through the system package manager or by invoking cURL, a client-side data transfer tool:


curl https://bootstrap.pypa.io/get-pip.py | python

One major advantage of pip is the ease of its command-line interface, which makes installing Python software packages as easy as issuing a command:


pip install some-package-name

Users can also easily remove the package:


pip uninstall some-package-name

Most importantly pip has a feature to manage full lists of packages and corresponding version numbers, possible through a "requirements" file.[4] This permits the efficient re-creation of an entire group of packages in a separate environment (e.g. another computer) or virtual environment. This can be achieved with a properly formatted requirements.txt file and the following command:


pip install -r requirements.txt

Install some package for a specific version python, where $version is replaced for 2, 3, 3.4, etc.:


pip$version install some-package-name

Can't figure out why I get Error loading static resource from app.xaml

Image
1 I having trouble getting my ResourceDictionary.MergedDictionaries to load from app.xaml. My WPF app has a static class with a Main defined and startup object set to it. Within Main I created an instance of App and run it. The override OnStartup fires and the mainwindow.cs InitializeComponent gives the error "Message "Cannot find resource named 'MaterialDesignFloatingActionMiniAccentButton'. If I put the resources in the mainwindow.xaml everything is fine, but I wanted them to load at the app level so I they are not in each page. Any help appreciated. public partial class App protected override void OnStartup(StartupEventArgs e) base.OnStartup(e); var app = new MainWindow(); var context = new MainWindowViewModel(); app.DataContext = context; app.Show(); from the Main.. var app = new App(); app.Run(); app.xaml.. <Application x:Class="GS.Server.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:...

How to fill missing numeric if any value in a subset is missing, all other columns with the same subset are missing

Image
up vote 2 down vote favorite There is a clear pattern that show for two separate subsets (set of columns); If one value is missing in a column, values of other columns in the same subset are missing for any row. Here is a visualization of missing data My tries up until now, I used ycimpute library to learn from other values, and applied Iterforest. I noted, score of Logistic regression is so weak (0.6) and thought Iterforest might not learn enough or anyway, except from outer subset which might not be enough? for example the subset with 11 columns might learn from the other columns but not from within it's members, and the same goes for the subset with four columns. This bar plot show better quantity of missings So of course, dealing with missings is better than dropping rows because It would affect my prediction which does contain the same missings quantity relatively. Any better way to deal with these ? [EDIT] The nullity pattern is confirmed: machine-learning cor...
