Attempt to Download freeimage failing #111

virtualbrown · 2014-12-31T00:05:09Z

Installed Moviepy on Mac.
Try to run the first time and the download of free image is failing.

Exception Type: IOError at /
Exception Value: Error while fetching file https://github.com/imageio/imageio-binaries/raw/master/freeimage/libfreeimage-3.16.0-osx10.6.dylib.
Dataset fetching aborted (init() got an unexpected keyword argument 'context')

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 ?

Zulko · 2014-12-31T07:23:22Z

Also can you give your Python version ?

almarklein · 2014-12-31T07:24:13Z

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

virtualbrown · 2014-12-31T17:44:28Z

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

                  'Dataset fetching aborted (%s)' % (url, e))

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!

almarklein · 2015-01-02T22:12:52Z

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?

virtualbrown · 2015-01-15T06:20:18Z

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

class HTTPHandler(AbstractHTTPHandler):

def http_open(self, req):
    return self.do_open(httplib.HTTPConnection, req)

http_request = AbstractHTTPHandler.do_request_

if hasattr(httplib, 'HTTPS'):
class HTTPSHandler(AbstractHTTPHandler):

    def __init__(self, debuglevel=0, context=None):
        AbstractHTTPHandler.__init__(self, debuglevel)
        self._context = context

    def https_open(self, req):
        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.

    http_class must implement the HTTPConnection API from httplib.
    The addinfourl return value is a file-like object.  It also
    has methods and attributes including:
        - info(): return a mimetools.Message object for the headers
        - geturl(): return the original request URL
        - code: HTTP status code
    """
    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)    <--- this is where the exception is thrown.

**http_conn_args is a dictionary containing

{'context': None}

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

almarklein · 2015-01-15T09:52:15Z

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).

virtualbrown · 2015-01-15T15:30:26Z

Hi.

I made the change but still get the same error.

Exception Type: IOError at /
Exception Value: Error while fetching file http://github.com/imageio/imageio-binaries/raw/master/freeimage/libfreeimage-3.16.0-osx10.6.dylib.

virtualbrown · 2015-01-16T05:22:12Z

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.

    http_class must implement the HTTPConnection API from httplib.
    The addinfourl return value is a file-like object.  It also
    has methods and attributes including:
        - info(): return a mimetools.Message object for the headers
        - geturl(): return the original request URL
        - code: HTTP status code
    """
    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)

almarklein · 2015-01-17T21:07:32Z

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 works

virtualbrown · 2015-01-17T22:28:46Z

I 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.

almarklein · 2015-01-17T23:02:14Z

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.

Zulko · 2015-01-17T23:07:13Z

I'm leaving the issue open just in case someone else has the same problem.

keikoro · 2017-02-18T20:40:02Z

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.
