running with suggested config file doesn't work

[Carldeboer]

Hi! Not sure this is a config problem or not (although running GPyOpt in python appears to work so far. Directly running the example from the tutorial here (http://sheffieldml.github.io/GPyOpt/firstexamples/index.html) gives me an error:

$ gpyopt.py config_ex.json
Traceback (most recent call last):
  File "/home/unix/cgdeboer/.conda/envs/GPyOptEnv/bin/gpyopt.py", line 20, in <module>
    bo = driver.run()
  File "/home/unix/cgdeboer/.conda/envs/GPyOptEnv/lib/python2.7/site-packages/GPyOpt/interface/driver.py", line 105, in run
    space = self._get_space()
  File "/home/unix/cgdeboer/.conda/envs/GPyOptEnv/lib/python2.7/site-packages/GPyOpt/interface/driver.py", line 38, in _get_space
    assert 'space' in self.config, 'The search space is NOT configured!'
AssertionError: The search space is NOT configured!

I also note that I can't find much in the way of documentation regarding the syntax of these config files.

Finally, the link at the bottom of this page (http://sheffieldml.github.io/GPyOpt/tutorial/index.html)
Check the GPyOpt documentation for details of the different functionalities.
is broken.

Same problem here, and unable to find json file specs. I think the documentation may have moved here (per #164), but I can't find anything about the config file there.

I meet the same problem, the code tutorial seems provide us with a wrong example.
I finally remove the bugs by changing the "variables" part of the json file to the code below：
"space" : { "x": { "name": "var_1", "type" : "continuous", "dimensionality" : 1, "domain" : "(-1,1)" }, "y": {"name": "var_2", "type" : "continuous", "dimensionality" : 1, "domain" : "(-2,2)" } },

meanwhile，add the below code into line93 of GPyOpt.core.task.space.py
space = [space['x'], space['y']]

But it seems like I will always need to change the space.py when changing variables.
