OSError: dlopen(myo, 6): image not found about myo-python HOT 10 CLOSED

It could be version dependent. The DYLD_LIBRARY_PATH solution works fine with 0.8.0. Haven't gotten a chance to try 0.8.1

from myo-python.

I just tried it with 0.8.1 as well. It works fine. Could you double check that the DYLD_LIBRARY_PATH holds the correct path (maybe there is a typo somewhere) to myo.framework?

Thanks @iawffe, yes this is the right place to report issues. Can you share the entire stacktrace with us?

Hi Juharris, when you say stacktrace do you mean the following message?

Hi sgzsh269,

I don't see any typo in the Path I gave to DYLD_LIBRARY_PATH

Unless I need to give the absolute path instead of starting with /LIBRARY???

Sorry I am really new to Mac so I don't know much.

from myo-python.

Sure try with the absolute path and let us know.

from myo-python.

I tried
export DYLD_LIBRARY_PATH=/Users/iawffe/Library/Myo_SDK/myo.framework
and
export DYLD_LIBRARY_PATH=/Users/iawffe/Library/Myo_SDK/

Both don't seem to work, throwing the same error. (*I open Terminal and key in the command, then I run the python script. I didn't close the Terminal, I don't think it would make any differences)

from myo-python.

Ok, I found something. If I did everything in the Terminal window it works.
e.g., Set DYLD_LIBRARY_PATH, navigate to the myo-python folder, run the script by typing python hello.py

The error I saw was in an IDE (spyder). I think there is something else I need to setup.

from myo-python.

Oh. You would need to permanently set your up your path
or DYLD_LIBRARY_PATH and the re-open your IDE. Usually IDE's only get the
path the first time they open.

from myo-python.

Feel free to continue the discussion here but I'm going to close this issue since it works in your Terminal. It also works in my IDE (Eclipse + PyDev).
