- xorbits.numpy.DataSource = <function DataSource>#
A generic data source file (file, http, ftp, …).
DataSources can be local files or remote files/URLs. The files may also be compressed or uncompressed. DataSource hides some of the low-level details of downloading the file, allowing you to simply pass in a valid file path (or URL) and obtain a file object.
destpath (str or None, optional) – Path to the directory where the source file gets downloaded to for use. If destpath is None, a temporary directory will be created. The default path is the current directory.
URLs require a scheme string (
http://) to be used, without it they will fail:
>>> repos = np.DataSource() >>> repos.exists('www.google.com/index.html') False >>> repos.exists('http://www.google.com/index.html') True
Temporary directories are deleted when the DataSource is deleted.
>>> ds = np.DataSource('/home/guido') >>> urlname = 'http://www.google.com/' >>> gfile = ds.open('http://www.google.com/') >>> ds.abspath(urlname) '/home/guido/www.google.com/index.html' >>> ds = np.DataSource(None) # use with temporary file >>> ds.open('/home/guido/foobar.txt') <open file '/home/guido.foobar.txt', mode 'r' at 0x91d4430> >>> ds.abspath('/home/guido/foobar.txt') '/tmp/.../home/guido/foobar.txt'
This method has not been implemented yet. Xorbits will try to execute it with numpy.
