CMB Likelihood

[NickHunt-Smith]

It seems that there is an issue with the yaml dumper when using the newly-added CMB likelihood test function:

File "rejection_sampling.py", line 91, in
experiment.run(function, finish_line=1000)
File "/home/nicholas/.local/lib/python3.8/site-packages/high_dimensional_sampling/experiments.py", line 247, in run
self._perform_experiment(function, log_data)
File "/home/nicholas/.local/lib/python3.8/site-packages/high_dimensional_sampling/experiments.py", line 88, in _perform_experiment
self.logger.log_experiment(self, function)
File "/home/nicholas/.local/lib/python3.8/site-packages/high_dimensional_sampling/experiments.py", line 620, in log_experiment
yaml.dump(info, handle, default_flow_style=False)
File "/usr/lib/python3/dist-packages/yaml/init.py", line 290, in dump
return dump_all([data], stream, Dumper=Dumper, **kwds)
File "/usr/lib/python3/dist-packages/yaml/init.py", line 278, in dump_all
dumper.represent(data)
File "/usr/lib/python3/dist-packages/yaml/representer.py", line 27, in represent
node = self.represent_data(data)
File "/usr/lib/python3/dist-packages/yaml/representer.py", line 48, in represent_data
node = self.yaml_representers[data_types[0]](self, data)
File "/usr/lib/python3/dist-packages/yaml/representer.py", line 207, in represent_dict
return self.represent_mapping('tag:yaml.org,2002:map', data)
File "/usr/lib/python3/dist-packages/yaml/representer.py", line 118, in represent_mapping
node_value = self.represent_data(item_value)
File "/usr/lib/python3/dist-packages/yaml/representer.py", line 48, in represent_data
node = self.yaml_representers[data_types[0]](self, data)
File "/usr/lib/python3/dist-packages/yaml/representer.py", line 207, in represent_dict
return self.represent_mapping('tag:yaml.org,2002:map', data)
File "/usr/lib/python3/dist-packages/yaml/representer.py", line 118, in represent_mapping

File "/usr/lib/python3/dist-packages/yaml/representer.py", line 52, in represent_data
node = self.yaml_multi_representers[data_type](self, data)
File "/usr/lib/python3/dist-packages/yaml/representer.py", line 317, in represent_object
reduce = data.reduce_ex(2)
File "stringsource", line 2, in classy.Class.reduce_cython
TypeError: no default reduce due to non-trivial cinit

For now I've just commented out the yaml dumper in line 619 of experiments.py.

Also just a heads up for the rejection sampling example, to find the right ranges for the CMB likelihood it should be ranges = function.ranges not ranges = function.get_ranges(0.01). check_testfunction should have also have function as an attribute.
