Problems on python run.py arm3 dmp write

[codelover618]

Hi, Travis,

When I run the code on Mac as this post says, an error
ImportError: dlopen(/Users/cl/Downloads/control-master/studywolf_control/arms/three_link/py3LinkArm.so, 2): no suitable image found. Did find: /Users/cl/Downloads/control-master/studywolf_control/arms/three_link/py3LinkArm.so: unknown file type, first eight bytes: 0x7F 0x45 0x4C 0x46 0x02 0x01 0x01 0x00
occurs.

Then I went the directory, deleting py3LinkArm.so file and run the command python setup.py build_ext -i, but many errors and warnings occurs,
21 warnings and 11 errors generated. error: command 'clang' failed with exit status 1.

So, how can I solve this problem?

Ah yeah, sorry the 3 link arm isn't supported on Mac. There's some compiling problems with it and since I only use Ubuntu I haven't debugged them. Sorry about that! The examples should work with the arm2_python on Mac though!

Thanks for replying! I will try to use Ubuntu to debug the code.

Besides, how the text file in tasks/write_data generate? They seem like the path of specified character? Can you give me some hints on generating them.

Thank you!

Great! It should hopefully compile for you without any issues in Ubuntu, if problems come up please let me know.

For generating the data I used a custom program that records trajectories drawn on a phone screen, it looks like though GIMP might have a way of doing it too: http://registry.gimp.org/node/25828

Hi, Travis,

Thank you for your reply. I have successful run the code in Ubuntu!

However, it doesn't work when I use 2 link arm as what you said before. I use this command python run.py arm2 dmp write (I don't sure whether it's right.) and the error below occurs(both in Mac and Ubuntu14.04):

Traceback (most recent call last):
  File "run.py", line 55, in <module>
    arm_module = importlib.import_module(name=arm_name)
  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
  File "/home/parallels/Downloads/control/studywolf_control/arms/two_link/arm.py", line 19, in <module>
    from . import py2LinkArm
ImportError: cannot import name py2LinkArm

What should I do to fix this?

[studywolf]

ah sorry, the one you want (that is pure python) is arm2_python not just arm2. The arm2 should hopefully work in Ubuntu after it's compiled like arm3 was, also!
