expected LockingPolicy

[Lycos2]

hello,
I'm a biginner in programming, i'm working on a project with myo to use it with people with Parkinson disease, a month earlier I used the myo master SDK to assure the connection and it worked but now the same script won't work (I didn't change anything) can you help me please to solve this issue :
runfile('C:/Users/ELYES/Desktop/myo_test/myo-python-master/01_hello_myo.py', wdir='C:/Users/ELYES/Desktop/myo_test/myo-python-master')
[autoreload of sitecustomize failed:

    self.locking_policy = LockingPolicy.none

TypeError: expected LockingPolicy

Hi Lycos2,

I can not reproduce it here. Could you help me debug this please?

In the _ffi.py file, please modify the Hub.locking_policy setter function starting at line 488 so that it reads

  @locking_policy.setter
  def locking_policy(self, policy):
    print('@@@', repr(policy), type(policy), type(policy).__module__, LockingPolicy.__module__, type(policy) is LockingPolicy)
    if not isinstance(policy, LockingPolicy):
      raise TypeError('expected LockingPolicy')
    error = ErrorDetails()
    libmyo.libmyo_set_locking_policy(self._handle[0], int(policy), error.handle)
    error.raise_for_kind()

After that, run your Python script again and please paste the output in the console.

Please put any terminal output in code blocks like so:

```
Code here

Hm that is weird. Something seems to be wrong with the enumeration types. Can you tell me the exact version of Python you are using and the version of the nr library that is installed?

python --version
python -c "import nr; print(nr.__version__)"

[Lycos2]

(base) C:\Users\ELYES>python --version
Python 3.6.5 :: Anaconda, Inc.

(base) C:\Users\ELYES>python -c "import nr; print(nr.version)"
1.3.5

[NiklasRosenstein]

How did you install myo-python?

We require nr>=2.0.10 which should have been upgraded automatically when you installed it via Pip. 😕

pip install 'nr>=2.0.10'

should fix your problem.

[Lycos2]

hi Niklas,
I updated nr to 'nr>=2.0.12' and i got that :

[NiklasRosenstein]

Uhm and what happens if you type import nr.enum in your Python interpreter?

[Lycos2]

I did that and it seems ok!!

Could you come over to https://gitter.im/NiklasRosenstein/myo-python? I have some more questions regarding your environment.
