# Fake Dataset Generator Documentation
## Introduction
The `generate_fake_dataset` function is designed to generate a fake dataset based on the provided configuration using the Faker library. This can be useful for testing, development, or generating sample data.
## Function Signature
```python
generate_fake_dataset(num_rows, path="fake_dataset.csv", none_values=True, table_head=None)
```
- `num_rows`: Number of rows to generate in the dataset.
- `path`: The path where the generated dataset will be saved. Default is "fake_dataset.csv".
- `none_values`: Whether to include None values in the generated dataset. Default is `True`.
- `table_head`: A dictionary specifying the columns and their configurations.
## Column Configuration
The `table_head` dictionary defines the columns of the dataset, where each key is the column name, and the value is a dictionary specifying the column configuration. Supported configurations include:
- `type`: Faker provider type (e.g., "name", "email", "passport_gender").
- `dtype`: Data type (e.g., "int").
- `range`: Range of values for integer columns (e.g., "1-100").
- `len`: Length of integer columns.
## Example Usage
```python
import pandas as pd
from faker import Faker
# Define the column configurations
table_head = {
"name": {"type": "name"},
"email": {"type": "email"},
"gender": {"type": "passport_gender"},
"age": {"dtype": "int", "range": "10-100"},
"score": {"dtype": "int", "range": "10-100"},
"time_s": {"dtype": "int", "range": "10-100"},
}
# Generate a fake dataset with 500 rows and save it to a CSV file
generate_fake_dataset(500, "sample.csv", True, table_head)
```
## Supported Faker Providers

# OCR Installation and Tesseract Path Finder
## Introduction
The provided Python script includes functions to install an OCR (Optical Character Recognition) tool from an installer executable and to find the path to the Tesseract OCR executable on the system.
## Functions
### 1. `install_ocr()`
This function installs an OCR tool using an installer executable. The installer file should be specified as `ocr.exe`. The function retrieves the current script's path, combines it with the installer filename to create the full installer path, and then attempts to run the installer using `subprocess.run()`.
#### Example Usage:
```python
# Example: Install OCR
install_ocr()
```
### 2. `find_tesseract()`
This function attempts to find the path to the Tesseract OCR executable. It first checks if Tesseract is installed in a specific path (`C:\Program Files\Tesseract-OCR\tesseract.exe`). If not found, it then tries to locate Tesseract in the system's PATH using `shutil.which("tesseract")`.
#### Example Usage:
```python
# Example: Find Tesseract Path
tesseract_path = find_tesseract()
if tesseract_path:
print(f"Tesseract found at: {tesseract_path}")
else:
print("Tesseract not found.")
```
## Important Note
- Ensure that the installer file (`ocr.exe`) is in the same directory as the script or provide the correct path to the installer in the `install_ocr()` function.
- For `find_tesseract()`, if Tesseract is not found in the specified path or in the system's PATH, it will return `None`.
## Recommendations
- Before using `install_ocr()`, verify that the installer file is compatible with your system.
- Make sure to have the necessary permissions to install software on the system.
- If you are installing from a source other than PyPI, ensure that it is trusted or has been verified by an individual who knows what they
