Deeplabcut: issue running imageio in step 1 (imageio installation for MacOS)

[maryeveh]

Hi,

I am trying to set up your pipeline on Mac OS El Capitan 10.11.6. I installed Jupyter Notebook to run the first step. When I run "imageio.plugins.ffmpeg.download()" I get the following error:
"Imageio: 'ffmpeg-osx-v3.2.4' was not found on your computer; downloading it now.
Error while fetching file: Error while fetching file: Error while fetching file:

Error while fetching file:

Did anything like that happen to you? Do you have a fix for it? I tried everything I could find online, but it did not help.
Thanks,
Marie

I am afraid, we are not using MacOS (but I think the code has already been used on MacOS). It seems that you also use python2.7. You should use 3.x; perhaps that solves the issue? Anyway, you could email Taiga Abe, one of the coauthors who I believe used the code on his Mac. Please send me an email and I can introduce you.

This really seems to be a imageio installation issue. So it would be great if someone else, who used it on MacOS could chip in.

Here is a quick update on the fix that worked for me on MacOS. It consisted in manually getting the ffmpeg certificate and package from the _Imageio GitHub repository_:

cd /Users/<username>/Library/Application\ Support/imageio
mkdir ffmpeg
cd ffmpeg
wget https://github.com/imageio/imageio-binaries/raw/master/ffmpeg/ffmpeg-osx-v3.2.4

Also I got an additional issue when running the commands with sk-image, which was easily solved by installing pillow version 5.0.0:

pip3 install pillow==5.0.0

Hope this might help.

I believe I ran into the same problem as you and ran the code you suggested, but used the curl command instead of wget since I'm on mac. I still got the following error...

/Users/cameronlaedtke/MLPracticeVE/bin/python /Users/cameronlaedtke/PycharmProjects/MLPractice/tSNEExample.py

os.path.basename(file_name))

Any idea what's going on?

With respect to wget/curl. I think @maryeveh suggests to literally go to https://github.com/imageio/imageio-binaries/raw/master/ffmpeg/ffmpeg-osx-v3.2.4 (in your browser and download it manually). So that there is no ssl certificate error.

[maryeveh]

I am not an expert in differences between curl and wget, but there are some differences in the way they complete downloads (https://daniel.haxx.se/docs/curl-vs-wget.html). Maybe curl does not download everything that is needed, aka no the ssl certificate.
You can use wget on Mac (I am using a Mac). You have to install homebrew by typing the following line in your terminal: /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Then you type brew install wget and it should install it.
I hope this helps.

It worked. Thanks!

Glad to hear it! Happy analyses!
