[python-users] MetPy thermo.cape_cin function

Hello, 
I'm trying to calculate cape, cin values with cape_cin function which can be 
found in MetPy thermo module, 
but I encounter the error: AttributeError: 'module' object has no attribute 
'cape_cin' 
Also I wanrt to calculate the SRH "Storm Relative Helicity", is there a formula 
in MetPy to do that? 
Kind Regards
