cannot run example scripts using BO code in python2.7, 3.4 and 3.5

[adhaka]

Summary:

When I tried to run the example scripts in the examples folder:

python bdm.py

I get this error:

File "/home/akash/anaconda2/envs/py34/lib/python3.4/site-packages/elfi/methods/bo/utils.py", line 76
start_points[:, i] = random_state.uniform(*bounds[i], n_start_points)
^
SyntaxError: only named arguments may follow *expression

I got this error both in 2.7 and 3.4. After this I tried to create a new environment and installed 3.5 virtually on anaconda, and tried to run it again, and this time I got this:
File "/home/akash/SheffieldML/GPy/core/parameterization/init.py", line 9, in
from paramz import ties_and_remappings, ObsAr
ImportError: cannot import name 'ties_and_remappings'

This is a GPy Error, because one of the dependency pacjkages: paramz is still uncompatible for python 3.5. Can you suggest something here which I should do with the installations to make it finally working.

Current Output:

The example scripts did not run and throw syntax errors.

Expected Output:

The example scripts did not run.

Hi,

ELFI requires Python 3.5 or greater, so your first 2 attempts were doomed because of that. :)

For the third one, did you follow the installation instructions? Which versions of GPy and Paramz did you install? At least more recent versions of Paramz work fine with Python 3.5+.

Yeah, ok I actually just used the pip version of paramz and GPy with 3.5, I will try to install them by specifying the version this time.

I finally installed it properly, I had some older version of GPy- 1.5 in the source directory which was throwing up errors, updating it to the latest version made everything fine.
