Running VideoFileClip multiple times in django gives me error

[abirafdirp]

let's say I created a basic web for converting youtube videos to gifs

this is my views in django code

context = RequestContext(request)
    if request.GET:
        link = request.GET.get('link','')
    url = link
    try:
        video = pafy.new(url)
    except:
        return render_to_response("generated/invalid.html", context)
    video = video.getbest()
    if os.path.isfile(os.getcwd()+'\\static\\'+video.title+'.gif')==True:
        gifpath=video.title+'.gif'
        context_dict = {'staticpath':gifpath}
        return render_to_response("generated/generated.html", context_dict, context)
    video.download(quiet=True)
    clip = (VideoFileClip(os.getcwd()+"\\"+video.title+'.'+video.extension).resize(0.4))
    clip.write_gif(os.getcwd()+'\\static\\'+video.title+'.gif', fps=9, opt='optimizeplus', loop=0)
    gifpath=video.title+'.gif'
    context_dict = {'staticpath':gifpath}
    return render_to_response("generated/generated.html", context_dict, context)

it works fine, but after I convert 2-5 videos (it's random) it gives me this error

from the looks of it, the cause is in the VideoFileClip method AttributeError

It will works again if I restart the django server, strange!!!

in the django debugger, the exception is [WinError 6] The handle is invalid

Tried it with windows 8.1 64 bit and windows 7 32 bit

THANKS FOR YOUR TIME

Are you sure that the videos are downloaded correctly ?

[abirafdirp]

after I turned on the downloading status, it's confirmed I downloaded the video, I can watch it too (uppest and lowest request)

this is the full traceback

and obviously running the script multiple times outside django works fine, I think it's django-moviepy related

Hi there, any progress on this strange behavior ?

[abirafdirp]

sorry for late reply and not closing the issue, yes it's working right now, I had to use celery to do it, thanks

I'm still running into this issue.- I'm trying to render about 100 videos (each one consists of several VideoFileClip subclips), but each time I render 5 videos or so, I get the "Handle is Invalid" error. I've had to restart & clear my Jupyter kernel after every 4-5 videos I make.
Any updates on this bug?

Same here, just started running this in a new notebook...

Thanks
I solved this problem
add clip.close() after write_gif()
