Mac setup about myo-python HOT 12 CLOSED

There are some relevant forum posts here on how to set it up.

Basically you need to add the sdk/myo.framework folder of the Mac SDK to your PATH. So if the folder is in /home/pdyba/myo/sdk/myo.framework, then add /home/pdyba/myo/sdk/myo.framework to your PATH.

Let me know if you get it working and I'll add the steps to the README.

I guess I assumed that you're using a Mac because you linked to those forum posts. So what are you using?

from myo-python.

I'm using mac os 10.10 and pycharm my myo files are at /library/frameworks/
and I'v got error:

Error loading "myo". Make sure that it is in your path.
Using Python 3
Traceback (most recent call last):
File "/Users/Piotr/PycharmProjects/myo_t1/hello_myo.py", line 9, in
myo.init()
File "/Users/Piotr/PycharmProjects/myo_t1/myo/lowlevel.py", line 125, in init
lib = ctypes.cdll.LoadLibrary(lib_name)
File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/ctypes/init.py", line 429, in LoadLibrary
return self._dlltype(name)
File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/ctypes/init.py", line 351, in init
self._handle = _dlopen(self._name, mode)
OSError: dlopen(myo, 6): no suitable image found. Did find:
myo: not a file

so I've forked Your version and added 2 comments:
https://github.com/pdyba/myo-python-1
lowlevel.py line 105 is the one more important I wanted to branch Your but could not push.
It works great now :)
Cheers ! :)

​​I see but if you add the folder containing myo to your PATH then it should work. So add '/Library/frameworks/myo.framework' to your PATH​. If you're running in the command line, do:

export PATH=$PATH:/Library/frameworks/myo.framework

from myo-python.

export PATH=$PATH:/Library/frameworks/myo.framework
does not work a) permanently b) at all
I've tried that before and even added that line to /etc/paths/
and got still the same error

I'm still having fun:
if pose == pose_t.double_tap:
system('say Look')
elif pose == pose_t.wave_in:
system('say I am')
elif pose == pose_t.wave_out:
system('say Your')
elif pose == pose_t.fist:
system('say Father')

That's right it's not a permanent solution. I'm not sure how to add stuff permanently to your PATH on Mac but once you do it, you'll have to close and re-open whatever program you're running the myo-python in (Terminal/IDE).

Also lol but it's "Luke" not "Look".

from myo-python.

it work permanently after adding to /etc/paths/ for terminal i can write "myo" and get -bash: /Library/frameworks/myo.framework/myo: cannot execute binary file
but I got still the same error in python - OSError

look was the point ;) but never mind I am thinking about a different use:
"Vaders choaking simulator" and I know that I'm only interested in "finger date" the one thing that does not ring a bell is "emg" but even when hand is immobilized it gives me "random" numbers so I'm wondering what would You use to focus just on the fingers ?

from myo-python.

You can probably train some model using the EMG data to figure out what the fingers are doing. I suggest a sequential classifier like a CRF or HMM. I recommend CRFsuite. Of course you'll have to label data yourself to say for each EMG array to say what they mean. I started doing something similar here in another branch to detect sign language using a HMM with Scikit Lean but that was before EMG was available so it uses the other data and didn't work very well. That code guides to user in order to tell them to do certain things and labels the data for you.

Anyway we're kinda going on a tangent about the initial issue. So you still can't get the library to work as is even though myo is in your PATH? Are you running this library in an IDE or in the Terminal?

from myo-python.

IDE Pycharm and terminal give me all the same error ;/ and I'm using pure copy from github.
command myo in terminal work perfectly... but

os.path.abspath('myo')
'/Users/Piotr/myo'
and it is as above at /Library/frameworks/myo.framework

from myo-python.

os.path.abspath doesn't try to find things in your PATH. It makes a path for the folder that you give it. So '/Users/Piotr/myo' makes sense for os.path.abspath to return. Could you try adding /Library/frameworks/myo.framework/myo to your PATH?

from myo-python.

Hey guys, the solution is to add the myo.framework directory path to DYLD_LIBRARY_PATH since the myo binary is a dynamic lib.
Already tried it, works properly!

from myo-python.

Awesome! I'll update the README tomorrow.
