Can't create environment.yml (Windows 10 - Anaconda)

Tried running DeOldify on the latest Winx64 version of Anaconda. However, the environment.yml creation always fails with numerous conflicts concerning incompatible packages. I tried downgrading conda and various other workarounds I found via google. Any ideas as to what might be causing the issue?

Ok so this is how I got it running on Windows 10 Step by step: Should note that I didnt fully got it working because Im not running CUDA graphics card, although I got the application up and running and am currently seeing if theres an option to run on CPU instead.

Download Anaconda from here: https://www.anaconda.com/distribution/#download-section. I got it running with Anaconda version (4.7.12) with python version 3.7 installer. During the installation process, you will be presented with two checkboxes. Choose the “recomended one” (the bottom one).

Download WGet from here: http://gnuwin32.sourceforge.net/packages/wget.htm (I went for the Complete package, except sources one or with md5Sum b4679ac6f7757b35435ec711c6c8d912)

Add PATH Variables to Windows (If you are unsure what Im referring to, just google how to add system path variables to windows) This step is ofc dependant on where you installed your software. In my case it looked like this:

C:\Users\XXX\AppData\Local\Continuum\anaconda3
C:\Users\XXX\AppData\Local\Continuum\anaconda3\Scripts
C:\Users\XXX\AppData\Local\Continuum\anaconda3\Library\bin
C:\Program Files (x86)\GnuWin32\bin

1. open either CMD / powershell / git bash, in a folder where you would like to download deOldify and write the following: git clone https://github.com/jantic/DeOldify.git DeOldify (If you are unsure what GIT is, download git bash from here: https://git-scm.com/downloads).

now write cd DeOldify in cmd.

Open environment.yml file inside deOldify folder. change its content to the following:

name: deoldify
channels:
- fastai
- conda-forge
- defaults
- pytorch
dependencies:
- python>=3.7.3
- fastai=1.0.51
- pytorch=1.0.1
- ffmpeg=4.1.1
- tensorboardX=1.6
- youtube-dl>=2019.4.17
- jupyterlab
- pillow=6.2.1
- pip:
  - ffmpeg-python==0.1.17
  - opencv-python>=3.3.0.10
  - wandb

Go back to cmd / gitBash or whatever, and write the following: conda env create -f environment.yml (this takes a long time), and although after a while it looks like nothing is happening, wait some more. it should say when its finished.

when previous step is done, write the following in cmd: conda activate deoldify If this step provides with an error like Git isnt inited or similar, open separate cmd window and open in same folder (deOldify folder). Depending on which editor you open, write the following: conda init cmd (if you opened cmd) conda init bash for Git bash, conda init powershell etc. restart all cmds.

open new cmd and write jupyter lab this step should take a while and when done should open a webApp running on port localhost port 8888.

Open separate cmd and write the following: wget https://www.dropbox.com/s/mwjep3vyqk5mkjc/ColorizeStable_gen.pth?dl=0 -O ./models/ColorizeStable_gen.pth --no-check-certificate (This will only work given we provided the C:\Program Files (x86)\GnuWin32\bin to windows PATH) (Should note that I created the folder models inside the deOldify folder beforehand and unchecked the attribute read-only, although unsure if you need to do that yourself)

Enter localhost on port 8888 (it should open automatically) and open eg: imagecolorizer.ipynb and go through the steps.

For me this is where it ended because Im not running CUDA although if you have nvidia card this shouldnt be an issue.

Yes that was the link. Thank you very much. Greatly appreciated. Have a nice day.
