Error During Generate: Certificate Verify Failed

[don1138]

Add-on, Application and OS versions

Dream Textures 0.0.3 Blender 3.3 Mac OS 10.15.7

Describe the bug

When generating a texture, two certificate issues caused it to fail.

1.) future: <Task finished name='Task-1' coro=<DreamTexture.dream_texture() done, defined at /Users/***/Library/Application Support/Blender/3.3/scripts/addons/dream_textures/__init__.py:448> exception=URLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)'))>

2.) urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)>

and perhaps related, no current event loop was found.

How to Reproduce

On Mac with same specs, generate new texture.

With a normal Python install there is a InstallCertificates.command file you can run to setup the certificates, but I don’t think blenders Python will have this. So maybe you can try this answer from SO: https://stackoverflow.com/a/61142526 Using Blender’s Python though. If that works for you, I will add that script to the addon.

[davidrwilliamson]

I have the same issue in Blender 3.3 on Ubuntu 20.04.5 LTS.

That SO script did not work, because the OpenSSL directory it looks for does not exist. ssl.get_default_verify_paths() returns DefaultVerifyPaths(cafile=None, capath=None, openssl_cafile_env='SSL_CERT_FILE', openssl_cafile='/home/sybren/buildbot-builder/linux_glibc217_x86_64_cmake/build_deps/deps/Release/ssl/cert.pem', openssl_capath_env='SSL_CERT_DIR', openssl_capath='/home/sybren/buildbot-builder/linux_glibc217_x86_64_cmake/build_deps/deps/Release/ssl/certs').

Sybren is a Blender developer so I suppose this is a Blender bug where their OpenSSL path has found its way in when compiling Python.

[felipejoribeiro]

I'm having the same problem. I tried to create the file structure but macOS doesn't allow me. Even with sudo su. It responds with. mkdir: sybren: Operation not supported.

[Teralink]

Dream Textures 0.0.5 was released 3 days ago. The release notes say 'fixes an error with macOS installation'. Does it solve the problem of this thread? Or is it something else?

[carson-katri]

@Teralink It attempted to fix a different error with CLIP model downloading. I do not know of a solution for this yet.

[YAFU]

I have the same issue in Blender 3.3 on Ubuntu 20.04.5 LTS.

From here: https://github.com/Rapptz/discord.py/issues/5968#issuecomment-716222434

After installing those packages you should run Blender from the same terminal where you executed the line "export SSL_CERT_DIR=/etc/ssl/certs"

SSL certificate error is gone, but now I get an error related to:

File "/media/TEMP/@Blender_Buildboot/blender/3.4/python/lib/python3.10/site-packages/transformers/tokenization_utils_base.py", line 1768, in from_pretrained raise EnvironmentError( OSError: Can't load tokenizer for 'openai/clip-vit-large-patch14'. If you were trying to load it from 'https://huggingface.co/models', make sure you don't have a local directory with the same name. Otherwise, make sure 'openai/clip-vit-large-patch14' is the correct path to a directory containing all relevant files for a CLIPTokenizer tokenizer. /media/TEMP/@Blender_Buildboot/blender/3.4/scripts/addons/dream-textures/async_loop.py:62: DeprecationWarning: There is no current event loop loop = asyncio.get_event_loop

[carson-katri]

@YAFU good find. You should be able to run the script in the dream textures addon directory dream_textures/stable_diffusion/scripts/preload_models.py to download those.

[YAFU]

@carson-katri I'm not sure what to do, just run preload_models.py? I get the following: https://pastebin.com/UxDjZ6Hq

I have Python 3.10 installed on my system now.

BTW, I am using addon dependencies installed from addon "install dependencies" button now (dependencies installed in /blender/3.4/python/ of master/buildbot 3.4 portable folder). For now I have abandoned trying the method of installing dependencies on the system.

[diramazioni]

@YAFU SSL_CERT_DIR=/etc/ssl/certs does work thanks! Just run "Install dependencies" again from the addon preferences and you are set

These steps fixed the issue for me.

im on ubuntu 18.04, this fixed the exact same issue for me too. i also ran "install dependencies" from the preference window again and everything worked as expected. thank you for the good find.

[Alzy]

I found the fix for this in another thread. Use the certifi module which is bundled with Blender as @john-shine proposed here. This example uses aiohttp but should lead you in the right direction even if you're using a different module.

import ssl
import certifi

sslcontext = ssl.create_default_context(cafile=certifi.where())
with aiohttp.Timeout(10):
        ......
        async with session.get(url, ssl=sslcontext) as response:
            ......
