[Feature]: Improve File Path Handling

[justivanr]

Description

Current path handling assumes that code will always be executed from the library's directory, making it difficult to use the the library's functionalities outside of it.

Problem

Tried calling some methods from the core.py script in another script (outside the library's directory), but got errors concerning folders or files not being found.

Proposed Solution

For instance, I have temporarly solved this by replacing the way you handle the now_dir in certain files as follows:

Old Code:

now_dir = os.getcwd()
sys.path.append(now_dir)

My Solution:

now_dir = os.path.realpath(__file__)
applio_dir_len = now_dir .find("Applio") + len("Applio")
now_dir = now_dir [:applio_dir_len]
sys.path.append(os.path.join(now_dir))

In other scripts, I had to add the current_directory to os.path.join for certain files. For instance, in the preparing_files.py script, I had to do this:

current_directory = os.path.realpath(__file__)
applio_dir_len = current_directory .find("Applio") + len("Applio")
current_directory= current_directory[:applio_dir_len]

def generate_config(rvc_version: str, sample_rate: int, model_path: str):
    # Added 'current_directory' to os.path.join
    config_path = os.path.join(current_directory, "rvc", "configs", rvc_version, f"{sample_rate}.json")
    config_save_path = os.path.join(model_path, "config.json")
    if not os.path.exists(config_save_path):
        shutil.copyfile(config_path, config_save_path)

Alternatives Considered

idk

code is made to work in applio, that’s our focus
