[![View Source On Gitee](https://mindspore-website.obs.cn-north-4.myhuaweicloud.com/website-images/r2.3.0rc2/resource/_static/logo_source_en.svg)](https://gitee.com/mindspore/docs/blob/r2.3.0rc2/docs/mindspore/source_en/note/api_mapping/pytorch_diff/linspace.md)

## torch.linspace

```python
torch.linspace(start,
               end,
               steps,
               *,
               out=None,
               dtype=None,
               layout=torch.strided,
               device=None,
               requires_grad=False
              )
```

## mindspore.ops.linspace

```python
mindspore.ops.linspace(start,
                       end,
                       steps
                      )
```

## Differences

API function of MindSpore is consistent with that of PyTorch.

MindSpore: The dtype of output Tensor is the same as the parameter `start`.

PyTorch: the dtype of output Tensor is determined by the parameter `dtype`.

## Code Example

```python
# PyTorch
import torch

output = torch.linspace(1, 10, 5, dtype=torch.float32)
print(output)
# tensor([1.0000, 3.2500, 5.5000, 7.7500, 10.0000])

# MindSpore
import mindspore as ms
from mindspore import Tensor, ops

start = Tensor(1, ms.float32)
limit = Tensor(10, ms.float32)
delta = Tensor(5, ms.int32)
output = ops.linspace(start, limit, delta)
print(output)
# [1. 3.25 5.5 7.75 10.]
