# Notes on Python
- Using \__init__.py will fail in docs. 

- Adding path of modules:
    ```Python
    import sys
    import os

    # Add the absolute path to the ./src folder
    sys.path.append(os.path.abspath(os.path.join(os.path.dirname(__file__), '../../../', 'src/PyThon/Utils/Performance')))

    # Now you can import normally
    from Performance_mesurements import average_performance,measure_performance
    ```

### Documantation
    To provide type checking of multiple types use __*Union*__
    ```Python
    from typing import Union, Optional, Tuple
    ```

### Interesting
interesting opencv doc: [Here](https://docs.opencv.org/4.x/d2/d96/tutorial_py_table_of_contents_imgproc.html)

## Pytorch
I don't know for what reason I can not use torch compile.  I get not enough SM.
```Python
# Compile model for better performance
if torch.cuda.is_available():
    model = torch.compile(model)
    print("Model compilation enabled")
```
I failed also.
```Python
# Enable gradient check-pointing
model_sequential = nn.Sequential(*list(model.children()))
model.forward = lambda x: checkpoint_sequential(model_sequential, 2, x)
print("Gradient check-pointing enabled")
```

TODO:
    Read [multiprocessing — Process-based parallelism](https://docs.python.org/3/library/multiprocessing.html)


### Path:
Separating path OS independently
```Python
import os
path.split(os.sep)
```
All components	Yes	Simple, but may give '' if path starts with / or drive letter present

## Matplotlib.pyplot

```Python
# Set Times New Roman as the font for all text
plt.rcParams['font.family'] = 'Times New Roman'
```
