dirname

fury.data.dirname(p)

Returns the directory component of a pathname

fetch_viz_icons

fury.data.fetch_viz_icons()

Download icons for fury

pjoin

fury.data.pjoin(a, *p)

copyfileobj

fury.data.fetcher.copyfileobj(fsrc, fdst, length=16384)

copy data from file-like object fsrc to file-like object fdst

copyfileobj_withprogress

fury.data.fetcher.copyfileobj_withprogress(fsrc, fdst, total_length, length=16384)

fetch_data

fury.data.fetcher.fetch_data(files, folder, data_size=None)

Downloads files to folder and checks their md5 checksums.

For each file in files the value should be (url, md5). The file will be downloaded from url if the file does not already exist or if the file exists but the md5 checksum does not match.

folder : str

The directory where to save the file, the directory will be created if it does not already exist.

data_size : str, optional

A string describing the size of the data (e.g. “91 MB”) to be logged to the screen. Default does not produce any information about data size.

Raises:

FetcherError

Raises if the md5 checksum of the file does not match the expected value. The downloaded file is not deleted when this error is raised.
