Frequently Asked Questions
Which types of data can the GLFM handle?
This model is specially suitable to deal with very heterogeneous data. There are currently five types of data defined:
- ‘g’: continuous real-valued
- ‘p’: continuous positive real-valued
- ‘n’: discrete count data
- ‘c’: discrete categorical
- ‘o’: discrete ordinal
Documented Errors in MATLAB
ERROR WITH MEX: GSL NOT FOUND (OS X)
mex -lgsl -lgmp -lgslcblas IBPsampler.cpp Building with ‘Xcode Clang++’. Error using mex In file included from GLFM/src/Ccode/wrapper_matlab/IBPsampler.cpp:1: GLFM/src/Ccode/wrapper_matlab/IBPsampler.h:6:10: fatal error: ‘gsl/gsl_sf_exp.h’ file not found #include <gsl/gsl_sf_exp.h> ^ 1 error generated.
To solve it, simply specify library location (where to look for the include) with -I flag
mex -lgsl -I/usr/local/include -lgmp -lgslcblas IBPsampler.cpp
Documented Errors in PYTHON
ERROR ASCII ENCODING INSTEAD OF UTF8
In case you get the following error at compilation time in Python:
UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xcc in position 32: ordinal not in range(128)
This error happens when the character encoding in your python version is not utf8 (the typical encoding).
To fix it, you might try to set up a new encoding as follows:
import sys
sys.setdefaultencoding('utf8')
More information available here: http://stackoverflow.com/questions/21129020/how-to-fix-unicodedecodeerror-ascii-codec-cant-decode-byte
The solution stated above only holds for the current session. To make it permanent, you might need to change site.py, the file where encoding is defined. You might replace the line:
encoding = “ascii” # Default value set by _PyUnicode_Init()
by
encoding = “utf8”
ERROR CYTHON.DISTUTILS
The following error occurs at compilation time when Cython has not been properly installed:
Traceback (most recent call last): File “setup.py”, line 2, in
from Cython.Distutils import Extension ImportError: No module named Cython.Distutils
Please install again Cython, following our Installation Instructions
ERROR PROXY
conda update –all Fetching package metadata …
CondaHTTPError: HTTP None None for url
Elapsed: None
An HTTP error occurred when trying to retrieve this URL. SSLError(SSLError(“Can’t connect to HTTPS URL because the SSL module is not available.”,),)
This error happens when proxy settings are ill-defined. This is a more general error that affects any other program as well. You might want to review your proxy settings. In OS X, you can check:
System Preferences > Network > Advanced > Proxies
