DATA_DIR#

fury.data.DATA_DIR()#

str(object=’’) -> str str(bytes_or_buffer[, encoding[, errors]]) -> str

Create a new string object from the given object. If encoding or errors is specified, then the object must expose a data buffer that will be decoded using the given encoding and error handler. Otherwise, returns the result of object.__str__() (if defined) or repr(object). encoding defaults to sys.getdefaultencoding(). errors defaults to ‘strict’.

update_progressbar#

fury.data.fetcher.update_progressbar(progress, total_length)[source]#

Show progressbar.

Takes a number between 0 and 1 to indicate progress from 0 to 100%.

copyfileobj_withprogress#

fury.data.fetcher.copyfileobj_withprogress(fsrc, fdst, total_length, *, length=16384)[source]#

check_sha#

fury.data.fetcher.check_sha(filename, *, stored_sha256=None)[source]#

Check the generated sha checksum.

Parameters:

  • filename (str) – The path to the file whose checksum is to be compared

  • stored_sha256 (str, optional) – Used to verify the generated SHA checksum. Default: None, checking is skipped

fetch_data#

fury.data.fetcher.fetch_data(files, folder, *, data_size=None)[source]#

Download files to folder and checks their sha checksums.

Parameters:

  • files (dictionary) – For each file in files the value should be (url, sha). The file will be downloaded from url if the file does not already exist or if the file exists but the sha 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 sha checksum of the file does not match the expected value. The downloaded file is not deleted when this error is raised.

fetch_gltf#

fury.data.fetcher.fetch_gltf(*, name=None, mode='glTF')[source]#

Download glTF samples from Khronos Group Github.

Parameters:

  • name (str, list, optional) – Name of the glTF model (for e.g. Box, BoxTextured, FlightHelmet, etc) KhronosGroup/glTF-Sample-Models Default: None, Downloads essential glTF samples for tests.

  • mode (str, optional) – Type of glTF format. You can choose from different options (e.g. glTF, glTF-Embedded, glTF-Binary, glTF-Draco) Default: glTF, .bin and texture files are stored separately.

Returns:

filenames – tuple of feteched filenames (list) and folder (str) path.

Return type:

tuple
