`treetensor` is a generalized tree-based tensor structure mainly developed by [OpenDILab Contributors](https://github.com/opendilab).
Almost all the operation can be supported in form of trees in a convenient way to simplify the structure processing when the calculation is tree-based.
## Installation
You can simply install it with `pip` command line from the official PyPI site.
```shell
pip install di-treetensor
```
For more information about installation, you can refer to [Installation](https://opendilab.github.io/DI-treetensor/main/tutorials/installation/index.html#).
## Documentation
The detailed documentation are hosted on [https://opendilab.github.io/DI-treetensor](https://opendilab.github.io/DI-treetensor/).
Only english version is provided now, the chinese documentation is still under development.
## Quick Start
You can easily create a tree value object based on `FastTreeValue`.
```python
import builtins
import os
from functools import partial
import treetensor.torch as torch
print = partial(builtins.print, sep=os.linesep)
if __name__ == '__main__':
# create a tree tensor
t = torch.randn({'a': (2, 3), 'b': {'x': (3, 4)}})
print(t)
print(torch.randn(4, 5)) # create a normal tensor
print()
# structure of tree
print('Structure of tree')
print('t.a:', t.a) # t.a is a native tensor
print('t.b:', t.b) # t.b is a tree tensor
print('t.b.x', t.b.x) # t.b.x is a native tensor
print()
# math calculations
print('Math calculation')
print('t ** 2:', t ** 2)
print('torch.sin(t).cos()', torch.sin(t).cos())
print()
# backward calculation
print('Backward calculation')
t.requires_grad_(True)
t.std().arctan().backward()
print('grad of t:', t.grad)
print()
# native operation
# all the ops can be used as the original usage of `torch`
print('Native operation')
print('torch.sin(t.a)', torch.sin(t.a)) # sin of native tensor
```
The result should be

## Extension
If you need to translate `treevalue` object to runnable source code, you may use the [potc-treevalue](https://github.com/potc-dev/potc-treevalue) plugin with the installation command below
```
pip install DI-treetensor[potc]
```
In potc, you can translate the objects to runnable python source code, which can be loaded to objects afterwards by the python interpreter, like the following graph
For more information, you can refer to
