Error while using label frames option of deeplabcut

OS: Windows 10
DeepLabCut Version: Deeplabcut '2.1.7.1'
Anaconda env DLC-CPU
Browser: chrome

Problem description
AssertionError while labeling frames. No option for 'loading frame' as shown in demo video

I tried through command prompt

cd
activate DLC-CPU
ipython
import deeplabcut
deeplabcut.launch_dlc()

Created project- and edited yalm file
Extracted frames-successfully extracted
Tried to label frames but got the following error in the attached screenshot.

I also tried to do the same procedure in ipython (without using GUI function) using command/functions of deeplabcut, but got the same error. I used the following commands.

IN: Import deeplabcut
IN: deeplabcut.create_new_project ('demo','chandu', ['A:\Test\Recall.mp4'])
Yaml file is generated---edited that file
path_config = 'A:\\DeepLabCut-master\\conda-environments\\demo-chandu-2020-05-09\\config.yaml'
IN: deeplabcut.extract_frames (path_config, 'automatic', 'kmeans')
Frames are extracted and you can label them using the function ‘lable_frames’
IN: deeplabcut.label_frames (path_config)

Screenshots
If applicable, add screenshots to help explain your problem.

[MMathisLab]

what version of wxPython are you using? Also, it would be much easier for you to copy / paste the code directly; your comment above is full of many mistakes, but I cant' tell if you really typed that exactly, or you typed it here incorrectly.

[alisonsin]

I have the same problem, I could not label the frame using GUI

[alisonsin]

This was the error message that I got

[MMathisLab]

@alisonsin could you please copy/paste the full terminal output so I can assess the error, thanks!

[MMathisLab]

because here is my test of the 2.1.7.1 code: (i.e. I cannot re-produce this error).

@MMathisLab thank you very much

[MMathisLab]

it looks like you are on MacOS? can you run:

pythonw -m deeplabcut

and see if the error persists? it may be that wxpython is not installed in ipython the same way...

[MMathisLab]

awe, looks like you didn't activate your env first, i.e. run

source activate DLC-CPU

then pythonw -m deepabcut

[MMathisLab]

or if you're not on MacOS, source activate DLC-CPU then python -m deeplabcut

[alisonsin]

I saw that in the label_frame subfolder, there's another subfolder created in which I saw images of frames-extracted in it. However, they are not labeled.

[chanduborkar]

Hi sorry for the typos here. However, I am sure that I did the correct command in cmd. I am using wx.__version: '4.1.0'

[MMathisLab]

@alisonsin looks like xcode needs updated. https://github.com/AlexEMG/DeepLabCut/wiki/Troubleshooting-Tips

These errors often occur after updating MacOS. The fix is to upgrade the Xcode toolkit as follows.
Open Terminal, and run xcode-select --install, followed by xcode-select --reset. Restart Terminal for changes to take effect. If the error persists, enter the command sudo xcode-select -switch /Library/Developer/CommandLineTools. Terminal will ask for your password; note that the password is not shown as you type.

^that is the expected behavior before you start labeling.

[chanduborkar]

@MMathisLab the error still persists. Did you find if any mistake I am doing? Thanks for your help!

[doursand]

hi,

I also have the same error, and my version of wx is 4.1.0 as well. My OS is ubuntu 16.04 (in fact a virtual ubuntu running on mac os x) . I will try to downgrade wx to '4.0.7.post2' and see if I still have the issue

[doursand]

Ok I confirm that the problem is solved for me if I install wxpython 4.0.7.post2 (instead of the latest release).

To do so, I downloaded the whl corresponding to my ubuntu version (16.04) from https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-16.04/

So for python 3.6, that was https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-16.04/wxPython-4.0.7.post2-cp36-cp36m-linux_x86_64.whl

Then in the folder where the whl file was downloaded, i simply did a

pip install wxPython-4.0.7.post2-cp36-cp36m-linux_x86_64.whl

after that i can open without any issue th GUI

[MMathisLab]

@alisonsin @chanduborkar could you both, inside the DLC environment:

pip install -U wxPython==4.0.7.post2

[alisonsin]

@MMathisLab It worked! Thank you very much!!

[MMathisLab]

I opened an issue - one of many - on their github (see link above); for now I pinned wxPython to an earlier version such that if one downloads the conda env again it should be fine for windows/macOS (https://github.com/AlexEMG/DeepLabCut/commit/da3908589e4bc97a258d65bca65da12fcd4dba24 / https://github.com/AlexEMG/DeepLabCut/commit/8e151c445b090061650596ea1aab2ac94380fa25). Ubuntu users, etc should continue to build from the appropriate wheel for now.

[chanduborkar]

@MMathisLab Thank you! It works!
