```auto
ImportError: cannot import name '_MODEL_URLS' from 'torchvision.models.mnasnet'

```

I am getting import error while import this:

```auto
from torchvision.models.mnasnet import _MODEL_URLS as URLs 

```

Any help would be highly appreciated.

The `_MODEL_URLS` `dict` was removed in [this PR](https://github.com/pytorch/vision/pull/5618). I don’t know what exactly you want to do with these URLs, but look at the PR to see how to use the introduced `weights` object to load the `state_dict`s.

Hi @ptrblck, I updated the torch version, and this issue is resolved. However, I am getting an unusual error while downloading datasets on pycharm IDE.

```auto
urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:997)>

```

my torch version is:

```auto
torch. __version__'1.12.1'

```

This issue is also fixed by importing these commands on download file:

```auto
import ssl
ssl._create_default_https_context = ssl._create_unverified_context

```
