I can do the following with a single int to retrieve a bool tensor:

```
import torch
a = torch.tensor([1,2,3])
a != 2
#tensor([ True, False, True])
```

Can I do the same with a list in plain pytorch? I.e.:

```
import torch
a = torch.tensor([1,2,3])
a not in [2,3]
#tensor([ True, False, False])
```

Thanks a lot for your time!

### >Solution :

I think you want `torch.isin`

```
out = ~torch.isin(a, torch.tensor([2, 3]))
# or
out = torch.isin(a, torch.tensor([2, 3]), invert=True)
```

```
print(out)
tensor([ True, False, False])
```
