I did pip install

Expected Behavior

I am making a face recognition program so it should work according .

Current Behavior

It showed me an error.

Anything else?

No response

Can you provide a reproducible example?

anshtyagi0 commented 8 months ago

you mean the code?

davisking commented 8 months ago

This is a problem some people run into, it's not related to dlib, but rather there is a broken copy of libgif on your system and dlib is trying to use it. Try grabbing the code from https://github.com/davisking/dlib/pull/2912 and installing from that with python setup.py install. That new cmake setup might realize to avoid the broken libgif. Let us know if that doesn't work and I'll tell you another way to definitely avoid it :)

anshtyagi0 commented 8 months ago

it says libgif not found while removing

davisking commented 8 months ago

I'm not sure what you mean by that. Post the output text of what you did.

anshtyagi0 commented 8 months ago

arrufat commented 8 months ago

@anshtyagi0 isn't it called giflib, at least that's what's called on Linux.

davisking commented 8 months ago

No I mean, get a copy of dlib from the git branch in https://github.com/davisking/dlib/pull/2912. Then do python setup.py install after first removing whatever copy of dlib you have. And then paste in what happens.

ok so while installing using GitHub I got this:

Looks like you already have dlib installed. Try uninstalling it first. pip uninstall dlib.

I already did that:

I don't know what that last part is about:

It shouldn't be talking to pypi.org if you are just using setup.py. That's a purely local thing and doesn't have any business talking to pypi about dlib.

So I don't know what to tell you. The other thing you could have done is say --no DLIB_GIF_SUPPORT as an option when installing. That will disable trying to use libgif at all and avoid that other problem. But I don't know why you are unable to install a python package like you are showing now.

anshtyagi0 commented 8 months ago

can you tell me about windows? will it work or not?

anshtyagi0 commented 8 months ago

@davisking just tell me this

davisking commented 8 months ago

It works on all platforms. I don't know why it's not working on your computer. Windows is fine too.

anshtyagi0 commented 8 months ago

actually I am trying to install face_recognition in that dlib is a dependency so I think that is causing some problem

anshtyagi0 commented 8 months ago

any other solution to this issue?

No solution found. If anyone finds then please reopen and ping me.
