I am running a python 2.7 code (containing GPy and GPyOpt, python implementation of gaussian process and Bayesian optimization) from Matlab on Anaconda 64bit on Windows 10 and I am facing with the following error:
warning in stationary: failed to import cython module: falling back to numpy Error using stationary>_gradients_X_cython (line 323) Python Error: NameError: global name 'stationary_cython' is not defined
When I run the code in python I do not have any problem, but the problem comes when I call the script from MATLAB (I have run the code from MATLAB a few months ago without any problem.)
I have to mention, recently for some reasons, I have downgraded the numpy to Numpy=1.11.0. That's because Matlab has a bug with the latest version of Numpy.
Also I am facing with the following window: An application has made an attempt to load the C runtime library ...
Q: Could you please help me to resolve the issue?
