How to import a file from the same directory in python?

Question

I have the following directory structure in python.

├── mel2samp.py
├── tacotron2
│   ├── layers.py

In mel2samp.py I want to import TacotronSTFT from tacatron2.layers using these lines of code

import sys
sys.path.insert(0, 'tacotron2')
from tacotron2.layers import TacotronSTFT

But it throws an error ImportError: No module named tacotron2.layers.

@Karl wouldn't that make just the folder importable in a way like `import tacotron2.layers` instead? He can still use it's own way with `sys.path` — denis_lor, Mar 13 '19 at 10:18
By adding `__init__.py` python recongnises the tacotron2 folder as a module. Otherwise you are going to have to extend sys.path for every single module you want to import — Karl, Mar 13 '19 at 10:21
Strange. I was unable to reproduce this problem. It ran without even an init fn. — J...S, Mar 13 '19 at 10:22
@J...S Maybe it is the problem of editor I am using it is vscode. Mostly it complains about such issues. — Samuel Mideksa, Mar 13 '19 at 10:25

Also need an empty __init__.py file in tacotron2 folder. After that you can do:

import sys
from tacotron2.layers import TacotronSTFT

I followed @Karl suggestion for the empty file – denis_lor Mar 13 '19 at 10:22

You don't need `sys.path.insert(0, '/tacotron2')` here. After adding `__init__` you can simply write `from tacotron2.layers import TacotronSTFT` – Karl Mar 13 '19 at 10:24

import sys
sys.path.insert(0, 'tacotron2')
from tacotron2.layers import TacotronSTFT
# Use TacotronSTFT

But it is recommended to make tacotron2 as a package by adding init.py

Then you can use it as

from tacotron2.layers import TacotronSTFT #Use TacotronSTFT

You can make your folder a package by adding __init__.py
You can read more about it here

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later (deeper) on the module search path. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable, described later.
