Dear list, I have a nested, layered state, and would like to do MCMC sampling; but state.copy(bs=bs, sampling=True) throws an error (below)... can this be fixed? Many thanks, Peter Traceback (most recent call last): File "code/model_averaging.py", line 38, in <module> state = state.copy(bs=bs, sampling=True) File "/share/apps/python/gcc6/2.7.12/lib/python2.7/site-packages/graph_tool/inference/nested_blockmodel.py", line 145, in copy **kwargs) File "/share/apps/python/gcc6/2.7.12/lib/python2.7/site-packages/graph_tool/inference/nested_blockmodel.py", line 109, in __init__ bstate = state.get_block_state(b=b, **args) File "/share/apps/python/gcc6/2.7.12/lib/python2.7/site-packages/graph_tool/inference/layered_blockmodel.py", line 532, in get_block_state **kwargs) File "/share/apps/python/gcc6/2.7.12/lib/python2.7/site-packages/graph_tool/inference/layered_blockmodel.py", line 149, in __init__ "layer_entropy"])) File "/share/apps/python/gcc6/2.7.12/lib/python2.7/site-packages/graph_tool/inference/blockmodel.py", line 408, in __init__ str(list(kwargs.keys()))) ValueError: unrecognized keyword arguments: ['copy_bg']
