DownloadError

class deepinv.utils.DownloadError(*args, **kwargs)

Bases: RequestException

Raised when a network download initiated by deepinv fails.

Wraps any underlying network error (HTTP status, connection failure, SSL error, DNS failure, timeout, …) so that callers — and the test suite in particular — can detect download failures with a single except DownloadError: rather than enumerating every exception type that the network stack may raise. The original exception is chained via __cause__.

Inherits from requests.exceptions.RequestException (and transitively from IOError) so existing handlers that catch those broader types keep working.
