Creating CFG fails

[simisimon]

With the following source code from the repository Conditional_Density_Estimation, the creation of the control flow graph fails.

def initialize_models(model_dict, verbose=False, model_name_prefix=''):
    ''' make kartesian product of listed parameters per model '''
    model_configs = {}
    for model_key, conf_dict in model_dict.items():
        model_configs[model_key] = [dict(zip(conf_dict.keys(), value_tuple)) for value_tuple in
                                    list(itertools.product(*list(conf_dict.values())))]

    """ initialize models """
    configs_initialized = {}
    for model_key, model_conf_list in model_configs.items():
        configs_initialized[model_key] = []
        for i, conf in enumerate(model_conf_list):
            conf['name'] = model_name_prefix + model_key.replace(' ', '_') + '_%i' % i
            if verbose: print("instantiating ", conf['name'])
            """ remove estimator entry from dict to instantiate it"""
            estimator = conf.pop('estimator')
            configs_initialized[model_key].append(globals()[estimator](**conf))
    return configs_initialized

Here is the corresponding stack trace. I think the line configs_initialized[model_key].append(globals()[estimator](**conf)) causes the error.

Thanks for the test case, I will push a fix tonight.

The bug is fixed now.
