matlab - MATLAB 网络保存错误

问题描述

每个人。

我正在尝试使用 MATLAB 进行语义分割的教程，参考以下链接。

https://kr.mathworks.com/help/vision/ug/semantic-segmentation-using-deep-learning.html

当我尝试以下部分时，我不断收到错误消息。

pretrainedURL = 'https://www.mathworks.com/supportfiles/vision/data/deeplabv3plusResnet18CamVid.mat';
pretrainedFolder = fullfile(tempdir,'pretrainedNetwork');
pretrainedNetwork = fullfile(pretrainedFolder,'deeplabv3plusResnet18CamVid.mat'); 
if ~exist(pretrainedNetwork,'file')
    mkdir(pretrainedFolder);
    disp('Downloading pretrained network (58 MB)...');
    websave(pretrainedNetwork,pretrainedURL);
end

错误消息的详细信息是

Error using websave (line 98)
Secure connection to
"https://www.mathworks.com/supportfiles/vision/data/deeplabv3plusResnet18CamVid.mat"
not established because "error setting certificate verify
locations:
  CAfile: /etc/ssl/certs/ca-certificates.crt
  CApath: none". Check your system certificates for expired,
  missing, or invalid certificates.

我搜索了这个问题的解决方案，但我找不到我想要的答案。

谁能帮我？谢谢。
