I hope somebody responds, I have the same issue.

EDIT: Well, @mesca, I got a temporary solution working, atleast for now. The installer provided in the repo does not seem to install plugin_interfaces. So, here are the steps I did :

1. Install openbci-python with pip

2. Clone this repo onto your machine.

3. Copy the file in the root called 'plugin_interface.py'

4. Then manually paste it into the plugins folder of the directory where openbci-python is installed. So for me the full path looked like:
   "C:\Users\tushar\AppData\Local\Programs\Python\Python35\Lib\site-packages\OpenBCI_Python-1.0.0-py3.5.egg\openbci\plugins"

5. In this directory (the 'plugins' directory), open each file, and see the imports, and replace all imports that say import plugin_interface as plugintypes with from . import plugin_interface as plugintypes. Do this with every file in the plugins directory.

6. Open your terminal (in any directory now), open python, then do from openbci import wifi, it should work. It works for me.

Hope you find this helpful!

If this works for you, please close the issue.

Thanks, but your solution and mine are just workarounds, not real fixes. The point is that I don't see the reason for importing ALL the plugins and dependencies in the __init__.py file, when you just need the wifi module.

Anyway, you should probably submit a PR, since at least that makes it useable. Having to manually copying and editing files defeat the purpose of a pip package ;)

I agree that having to manually copy and paste and edit files is definitely not something that the user should have to do. However, I wonder what exactly causes this issue. Is the setup.py not able to do a system-wide install of plugin_interfaces ? If so, then how would we fix that?

Well, I think it's because plugin_interface.py is not into the openbci package.

By openbci package, you mean the one install through pip, correct?

Yes, but also the normal Python package in the openbci directory (see: https://docs.python.org/3/tutorial/modules.html#packages).

Oh, I'm sorry I didn't get you the first time. Anyway, I have submitted a PR. Also, here is a version I made that you can install (still from the .whl file there). So you have to install manually. Here is the link -> https://github.com/tushar-c/openbci-fixed

EDIT: To make sure I'm clear, by manually, I mean you have to download, go to where the .whl file is, then do pip install <package>.

Sounds like we need to add the plugin_interface.py into the package that is published with pypi?

Probably :)

any ideas how?

Since this basically breaks the whole package ( I can't even do from openbci import cyton ), I feel like this should be a much higher priority ?

Just going to confirm that this issue is still present as of today after installing with pip install openbci-python. Also had to install pyserial "manually" (even though it's in requirements.txt - has the build on PyPi not been updated for a while or something?)

this error occurs on a new install ( fresh vm ubuntu 18.10) same error trying to import anything from the obenbci pkg fails.

upgrading pip and reinstalling did the trick

works fine

This is still not working for me, and as @rivasd said higher up in this thread, it breaks the whole package.

$ pip list
Package        Version
-------------- -------
bluepy         1.3.0  
future         0.17.1 
iso8601        0.1.12 
numpy          1.17.2 
OpenBCI-Python 1.0.2  
pip            19.2.3 
pyserial       3.4    
PyYAML         5.1.2  
setuptools     40.8.0 

Running the following code still throws an error:

import sys
from openbci import OpenBCIGanglion

def handle_data(sample):
    logging.debug(sample)

if __name__ == '__main__':
    board = OpenBCIGanglion()
    board.start_streaming(handle_data)

File "{...}/OpenBCIClient/venv/lib/python3.7/site-packages/openbci/plugins/csv_collect.py", line 6, in <module>
    import plugin_interface as plugintypes
ModuleNotFoundError: No module named 'plugin_interface'

@molguin92 I think that OpenBCI_Python is pretty much deprecated at this point, you should try out the pyOpenBCI repo/package instead, It works for bluetooth.
