我想从 Dropbox 或 UCF-Crime 视频数据集下载一个重压缩的 zip 文件。数据集的网站指出了从以下两个链接获取数据集的链接：
- https://www.dropbox.com/sh/75v5ehq4cdg5g5g/AABvnJSwZI7zXb8_myBA0CLHa?dl=0
- https://visionlab.uncc.edu/download/summary/60-data/477-ucf-anomaly-detection-dataset
每次我尝试通过 wget 或 curl 下载数据集时都会失败。我知道我在尝试错误的方法。我的示例将 visionlab url 作为参数。
wget https://visionlab.uncc.edu/download/summary/60-data/477-ucf-anomaly-detection-dataset/UCF-Anomaly-Detection-Dataset.zip
或者
curl https://visionlab.uncc.edu/download/summary/60-data/477-ucf-anomaly-detection-dataset/UCF-Anomaly-Detection-Dataset.zip
在每次试验中，我都会遇到以下错误消息：
ERROR: cannot verify visionlab.uncc.edu's certificate, issued by ...
Unable to locally verify the issuer's authority.
To connect to visionlab.uncc.edu insecurely, use `--no-check-certificate'.
编辑：我尝试通过启用该--no-check-certificate选项来下载数据集。但是，我收到以下消息：
wget --no-check-certificate https://visionlab.uncc.edu/download/summary/60-data/477-ucf-anomaly-detection-dataset/UCF-Anomaly-Detection-Dataset.zip
