Simple Installation??

[vhall413]

I am not a programmer. I am an artist who loved the results of the demo of this program, and I wanted to download it so I may use it as a base in my own works, to then work off of and create finalized art.

Unfortunately, the instructions might as well be in an ancient nordic language because I cannot for the life of me figure out how to install it. I feel as though I wasted several hours of my life downloading all these programs like the guide told me, only to be stumped at the last few lines that have no instructions, just coding (which means nothing to me as I have no idea what to do with them). So hours later, I am still incapable of using this program.

Is there no way for someone to package this into one install? Or at the very least, provide instructions that someone who is NOT a programmer may follow?

I see , current installation process is too difficult for non programmer. Currently we dont have 1 packaged version, its future work.

[vhall413]

a programmer friend helped me local install, but now i need a bit of help. all images i upload say they're too big to colorize. is there a way to allow larger image sizes?

[vhall413]

Wait, more issues.

I installed locally through python 3. The only way I've managed to get it to run is through a local server run through the command prompt. All other methods give various errors.

It opens perfectly with a local server, except uploading any image comes up with "UPLOAD ERROR". Any suggestions?

[kanekirsten07]

Having the same issue. managed to get it to lauch into localhost with

python -m http.server --cgi 8000 but I keep getting a code 501: can only post to CGI scripts error.

[taizan]

To colorize larger image, you have to change code itself. see also https://github.com/pfnet/PaintsChainer/issues/92

Did you booted the server.py ? is there any error in your console? python -m http.server --cgi 8000 is not correct command.
Type python server.py in your terminal at root PaintsChainer dir.

[kanekirsten07]

It's giving me the error "no module named http.server"

Which is odd because i'm using 3.6. I thought http.server was in python 3 :/

[kanekirsten07]

Oops, apologies. Forgot to input "python" >_>

Could have sworn i installed cudnn correctly :(

• Didn't tested in 3.6 but it fails to install in a month ago. Prefer 3.5 as stated in installation guide.
• FileNotFoundError: [Errno 2] No such file or directory: './cgibin/paint_x2_unet/models/unet_128_standard' Download the trained data. The network is nothing without trained data :)

For installation, due to license issues, we cannot include everything from the others. You must visit them all to get the "ingredients" legally. Here is just a recipe for making a roast chicken. (And this is why I created the guide to make it working in my personal notebook instead of big server)

[kanekirsten07]

ah, makes sense.

Sorry, having trouble understanding where to get the trained data and where to put it. I see the line, out, and ref folder in the images subfolder, but I'm unsure how to continue.

[6DammK9]

Visit http://paintschainer.preferred.tech/downloads/ Download all of them, put them into 'cgi-bin/paint_x2_unet/models/' Create folder models if you don't see it. cgi-bin should be in the same folder as server.py

[kanekirsten07]

Excellent! I can now upload images without upload error.

Unfortunately I'm now getting a "Server Error" after i upload and paint it. I don't think the image is too big, as I haven't received the 'Image is too large to colorize" error.

Any ideas? Hopefully it's not a python 3.6 error :/

[6DammK9]

You should see there are tons of logs in the console log. Try to copy and paste it here. If you can read it, try to paste the critical lines (Usually located in the bottom line).

[kanekirsten07]

Nothing in the command line:

python server.py GPU: 0 start load model serving at localhost : 8000

[6DammK9]

Try press F12 in browser... ? That could have a few lines about error.

I have a bad news for you (chill it happens to me too). What GPU you're using?

[kanekirsten07]

EVGA Geforce GTX 970. Almost brand new card :/

[kanekirsten07]

Updating my driver real quick....

[6DammK9]

Strange. Deprecate architecture occurs on GPU under 630... (Even 590 is included). That's may not your case. Ignore the warning. But for cl.exe See https://github.com/pfnet/PaintsChainer/wiki/Required-environment-variables Hard to explain it, try go to My Computer right click Properties > Advanced system options in the left > Environment variables and set them all. Make sure your VS stuffs are present.

[kanekirsten07]

I've tried adding D:\Program Files (x86)\Visual Studio\VC\bin to the environment path and tested a dozen or so times now and I still keep getting the same error.

Edit: is it a particular architecture it's looking for? I have amd64_arm, x86..etc. folders as well containing gl.exe, and i haven't been able to get it to work with any of them

[6DammK9]

Sorry for late reply. As my case, all folders have cl.exe, but /bin only is good enough. Go to the directory same as server.py Try use python to run these code

import os
print(os.environ["PATH"])

See if your D:\Program Files (x86)\Visual Studio\VC\bin exists there... If not, try make the environment variables not for your account but the system one. (there are 2 places to input them).

[Ulf3000]

i tried to run it locally , but both firefox and chrome tabs crash or hang

[bekhzod-olimov]

Hi, guys! @taizan, @kanekirsten07, @Ulf3000, @6DammK9, @vhall413, could anyone please share the downloaded pretrained models (unet_128_standard & unet_512_standard)? I cannot download them since the provided link in the repo does not function properly :(
