I get this error when I try to compute the thermo for H2 atom in cantherm ....

Generating Wilhoit thermo model for H2...
c:\Python27\lib\site-packages\scipy\optimize\optimize.py:988: RuntimeWarning: in
valid value encountered in absolute
q = abs(q)
c:\Python27\lib\site-packages\scipy\optimize\optimize.py:993: RuntimeWarning: in
valid value encountered in absolute
if ( (abs(p) < abs(0.5_q_r)) and (p > q*(a-xf)) and \

The line where it is failing is
scipy.optimize.fminbound(self.__residual, 300.0, 3000.0, args=(Tdata, Cpdata, Cp0, CpInf, H298, S298))

Currently I dont know what is the best way to fix this.
