Download Visual Studio Code for macOS. Open the browser's download list and locate the downloaded archive. Extract the archive contents. Use double-click for some browsers or select the 'magnifying glass' icon with Safari. Drag Visual Studio Code.app to the Applications folder, making it available in the macOS Launchpad. Mac Download Command Line Tools Run the following command from the Windows virtual machine and make a note of the IPv4 address: ipconfig.exe Within your application, change the endpoint URL to use the IPv4 address returned by ipconfig.exe instead of localhost. Brew tap mongodb/brew. If you have already done this for a previous installation of MongoDB, you can skip this step. To install MongoDB, run the following command in your macOS Terminal application: brew install mongodb-community@5.0. Alternatively, you can specify a previous version of MongoDB if desired.
NLTK comes with many corpora, toy grammars, trained models, etc. A complete list is posted at: http://nltk.org/nltk_data/
To install the data, first install NLTK (see http://nltk.org/install.html), then use NLTK’s data downloader as described below.
Apart from individual data packages, you can download the entire collection (using “all”), or just the data required for the examples and exercises in the book (using “book”), or just the corpora and no grammars or trained models (using “all-corpora”).
Interactive installer¶
For central installation on a multi-user machine, do the following from an administrator account.
Run the Python interpreter and type the commands:
A new window should open, showing the NLTK Downloader. Click on the File menu and select Change Download Directory. For central installation, set this to C:nltk_data (Windows), /usr/local/share/nltk_data (Mac), or /usr/share/nltk_data (Unix). Next, select the packages or collections you want to download.
If you did not install the data to one of the above central locations, you will need to set the NLTK_DATA environment variable to specify the location of the data. (On a Windows machine, right click on “My Computer” then select Properties>Advanced>EnvironmentVariables>UserVariables>New...)
Test that the data has been installed as follows. (This assumes you downloaded the Brown Corpus):
Installing via a proxy web server¶
If your web connection uses a proxy server, you should specify the proxy address as follows. In the case of an authenticating proxy, specify a username and password. If the proxy is set to None then this function will attempt to detect the system proxy.
Command line installation¶
The downloader will search for an existing nltk_data directory to install NLTK data. If one does not exist it will attempt to create one in a central location (when using an administrator account) or otherwise in the user’s filespace. If necessary, run the download command from an administrator account, or using sudo. The recommended system location is C:nltk_data (Windows); /usr/local/share/nltk_data (Mac); and /usr/share/nltk_data (Unix). You can use the -d flag to specify a different location (but if you do this, be sure to set the NLTK_DATA environment variable accordingly).
Run the command python-mnltk.downloaderall. To ensure central installation, run the command sudopython-mnltk.downloader-d/usr/local/share/nltk_dataall.
Windows: Use the “Run…” option on the Start menu. Windows Vista users need to first turn on this option, using Start->Properties->Customize to check the box to activate the “Run…” option.
Test the installation: Check that the user environment and privileges are set correctly by logging in to a user account,starting the Python interpreter, and accessing the Brown Corpus (see the previous section).
Manual installation¶
Mac Download Command Lines Files
Create a folder nltk_data, e.g. C:nltk_data, or /usr/local/share/nltk_data,and subfolders chunkers, grammars, misc, sentiment, taggers, corpora,help, models, stemmers, tokenizers.
Mac Download Command Line Tools
Download individual packages from http://nltk.org/nltk_data/ (see the “download” links).Unzip them to the appropriate subfolder. For example, the Brown Corpus, found at:https://raw.githubusercontent.com/nltk/nltk_data/gh-pages/packages/corpora/brown.zipis to be unzipped to nltk_data/corpora/brown.
Mac Download Data Command
Set your NLTK_DATA environment variable to point to your top level nltk_data folder.
