: This function was not present in torch.hub in versions prior to 1.2.0 .
The most permanent fix is to update your environment to a modern version of PyTorch (1.2.0 or higher). Most stable releases now include this function as a standard part of the torch.hub module. : pip install --upgrade torch torchvision Use code with caution. Using Conda : conda update pytorch torchvision -c pytorch Use code with caution. 2. Change the Import Name : This function was not present in torch
: In some development or transitional versions, the function was prefixed with an underscore ( _download_url_to_file ) to indicate it was an internal utility. Step-by-Step Solutions 1. Upgrade PyTorch (Recommended) : pip install --upgrade torch torchvision Use code
# Change this: from torch.hub import download_url_to_file # To this: from torch.hub import _download_url_to_file as download_url_to_file Use code with caution. 3. Use the Legacy Path Change the Import Name : In some development
The function download_url_to_file is a utility within PyTorch used to download remote files to a local cache. This error typically arises for two reasons:
Alternatively, you can manually download the .pth weight file and load it using torch.load() to avoid network-related import issues altogether.
In some older versions, the function resided in a different submodule entirely. You can try importing it from torch.utils.model_zoo :
