9 years ago Damn. Have you tried a second and third time just to be sure it wasn't a connexion problem (the error looks like a more serious issue but we never know).
@almarklein, any idea ?

9 years ago The Dataset fetching aborted (__init__() got an unexpected keyword argument 'context') is surprising, because it seems to originate from elsewhere (urllib?)

9 years ago Below is the full trace.
It seems to be bombing out in
File "/usr/local/lib/python2.7/site-packages/imageio/core/fetching.py" in _fetch_file
I've tried this several times with no luck. Also I manually downloaded the requested file and that works fine.
Any chance there is a workaround here where I can manually install freeimage? :)
Thx!

9 years ago Interesting. That last line in fetching.py actually catches an error and reraises it. I would very much like to know the original source. Can you try commenting the lines in imageio/core/fetching.py where the catching is done (in _fetch_file)? Or maybe find out the real source via debugging?

9 years ago Sorry just now getting back to this. I traced this down in to urllb2.py.

return self.do_open(httplib.HTTPConnection, req)
http_request = AbstractHTTPHandler.do_request_if hasattr(httplib, 'HTTPS'): class HTTPSHandler(AbstractHTTPHandler):

AbstractHTTPHandler.__init__(self, debuglevel)
self._context = context

return self.do_open(httplib.HTTPSConnection, req,
context=self._context) <---- this is failing. _context is None. See do_open below.def do_open(self, http_class, req, **http_conn_args): """Return an addinfourl object for the request, using http_class.

host = req.get_host()
if not host:
raise URLError('no host given')

LMK if you need more. I'm not familiar enough with urllib to really understand what is going on there.

9 years ago From a brief look, I think this may be related to certificates. Can you please try changing https:// into http:// (i.e. remove the "s") in:
_url_root = 'https://github.com/imageio/imageio-binaries/raw/master/'in fetching.py (line 47 in master).

9 years ago Hi.
I made the change but still get the same error.

9 years ago I made the following change in urllib2.py line 1166 and it worked. At least this got the library to install.
def do_open(self, http_class, req, **http_conn_args): """Return an addinfourl object for the request, using http_class.

host = req.get_host()
if not host:
raise URLError('no host given')
# will parse host:port
#h = http_class(host, timeout=req.timeout, **http_conn_args) <--- commented this out.
h = http_class(host, timeout=req.timeout)Changing your urllib2.py file is not a very nice solution; it might break other code. Are you sure the http thing did not work? Because if you look at the code for http_open vs https_open you see the http version omits the context argument, which seems to be triggering the problem.
To be absolutely sure could you try just calling:
path = 'imageio/imageio-binaries/raw/master/freeimage/libfreeimage-3.16.0-osx10.6.dylib'
urlopen('https://github.com/' + path) # should fail
urlopen('http://github.com/' + path) # I hope this worksI tried that code and the http call fails as well with the following error.
init() got an unexpected keyword argument 'context' (<type 'exceptions.TypeError'>)
I'm pretty new to Python is it possible that I have incompatible libraries (based on version) somehow?
Also, regarding my tweak of urllib2, after I was able to download the file...I changed it back. I just needed a way to get around the download.

9 years ago I am not sure about the cause. It seems rather specific to your system. I was hoping we could find a way to change imageio to avoid the error, but it seems this is not possible.
I am glad you solved your problem. Let's hope your case was a rare exception.

7 years ago I'm closing this issue as it sounds like OP solved their problem and 2+ years later, no-one else has commented to have run into the same problem.
Installed Moviepy on Mac. Try to run the first time and the download of free image is failing.
