SSL: CERTIFICATE_VERIFY_FAILED while trying to download pretrained model #33288

muxgt · 2020-02-13T12:58:28Z

🐛 Bug

Trying to use pretrained model from torchvision and receiving urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:852)> when downloading. In similar issues #33233 and #33234 it was said that problem is solved but I'm facing the issue right now.

To Reproduce

vgg16 = torchvision.models.vgg16(pretrained=True)

Expected behavior

Pre-trained models should be downloaded without certificate failures

Same thing when trying to pip install pytorch:

pip install torch===1.4.0 torchvision===0.5.0 -f https://download.pytorch.org/whl/torch_stable.html

Mxbonn · 2020-02-13T13:48:19Z

I'm having the same issue just now.
Check pytorch/vision#1876 for the main issue in the torchvision repository.

Aquassaut · 2020-02-13T14:07:30Z

@Mxbonn I don't think it is the same issue. This issue is that the SSL certificate for download.pytorch.org expired today :)

xen0f0n · 2020-02-13T16:08:38Z

@Mxbonn @Archetype90 until the certificate gets renewed, you can download the .whl you need from here and install it using pip.

optimuspaul · 2020-02-13T16:11:12Z

@xen0f0n that doesn't help us download pertained models. Our entire inference pipeline is dead in the water right now because we can't download the models.

albanD · 2020-02-13T16:18:02Z

You can use the same trick of using http instead of https as a temporary workaround.

Lissanro · 2020-02-13T16:24:05Z

I encountered the same issue when downloading resnet152 after calling cnn_learner(data, models.resnet152, metrics=error_rate). As a workaround, I downloaded it manually without checking certificate (using http instead of https is another option):

cd ~/.cache/torch/checkpoints/
wget -c --no-check-certificate https://download.pytorch.org/models/resnet152-b121ed2d.pth

albanD · 2020-02-13T16:34:12Z

Should be fixed now. Can you confirm it works for you?

soumith · 2020-02-13T16:35:59Z

The SSL Certificate issue is fixed now. The Cert was expired for ~4 hours, and we root-caused the auto-renewal problem, it wont happen again.

Neoanarika · 2020-05-23T03:19:06Z

Hi, I am having the same issue today on Mac OS X 10.14.6 when I tried to install pre-trained model of VGG.

jiangyuang · 2020-05-29T02:23:56Z

I'm having the issue again while trying to download Resnet18 (Edit: it has a problem on MacOS but fine on Ubuntu)

stephenllh · 2020-06-03T14:54:50Z

Having the same issue today when trying to download SEResNeXt-32x4d.

Having issues in downloading se_resnext50_32x4d(),
SSL expired.!

hot9cups · 2020-06-08T11:30:17Z

I have the issue while trying to download Inception resnet V2

!pip install pretrainedmodels
!pip install efficientnet-pytorch
from pretrainedmodels.models.inceptionresnetv2 import inceptionresnetv2
model_transfer = inceptionresnetv2(pretrained='imagenet')

I ran this on colab
The following was the output:

But, when I set pretrained = False, the model gets downloaded just fine.
How do I solve this?

will-maclean · 2020-06-12T22:30:34Z

Same issue downloading pre-trained vgg

hot9cups · 2020-06-13T05:59:05Z

Okay, my problem didn't have to do with PyTorch itself, I was downloading the model from Cadenn, and that has some problems with the certificate.
A workaround to that is mentioned here
With that, my problem was solved, might help someone else as well.

If anyone's short of time and can't wait till this is fixed, they can use the following hack: Just put these lines at the top of your codebase, and then run the same code again

import ssl
ssl._create_default_https_context = ssl._create_unverified_context

Thanks @adityasaini70 , This worked. Can you explain what we did here?

BenjaminPoole · 2021-12-06T18:21:17Z

@adityasaini70, Thanks this worked for me as well.

danton721 · 2022-04-03T03:25:58Z

The SSL Certificate issue is fixed now. The Cert was expired for ~4 hours, and we root-caused the auto-renewal problem, it wont happen again.

it happened, https://download.pytorch.org/ seems to have invalid certificates again, just letting you know

knimet · 2022-04-03T03:29:03Z

same issue

hit the same now, WAR still works:

RachitBansal · 2022-04-04T07:06:27Z

Yes, facing the same issue while downloading resnet50.
@adityasaini70's solution still works.

lamoboos223 · 2022-10-22T20:26:47Z

the issue is back again
