How to make tmdq progress bar for multilprocess

To create a TMDQ (Terminal Multiline Display Queue) progress bar for multiprocessing in Python, you can use the `tqdm` library, which provides an easy-to-use interface for displaying progress bars and is compatible with multiprocessing tasks. Here's a simple example on how to do it:

1. **Install tqdm**: If you haven't installed `tqdm`, you can do so using pip:

   pip install tqdm

2. **Import necessary libraries**:

   from multiprocessing import Process
   from tqdm import tqdm

3. **Create a function that performs some process and updates the progress bar**:

   def worker(counter, total):
       for i in tqdm(range(total), desc="Processing", unit='tasks'):
           # Your processing code here
           time.sleep(0.1)  # Simulate some work
           counter.value += 1

In this example, we use `desc` for the description of the progress bar and `unit` for the unit of progression.

4. **Use `multiprocessing.Process` and `Manager()` objects**:

   manager = Manager()
   counter = manager.Value('i', 0)
   processes = []

   # Create multiple processes
   for _ in range(num_processes):
       p = Process(target=worker, args=(counter, total_tasks))
       processes.append(p)
       p.start()

   # Wait for all processes to finish
   for p in processes:
       p.join()

   print("All tasks completed.")

5. **The progress bar will update automatically as each process calls the `counter.value += 1` line**. Make sure each process has access to the shared `counter` object through the `manager`.
