data type and logarithm

[afylot@gmail.com]

I tried to cast it to float by

rho = float(np.append(rho,columns[0]))

but I get

TypeError: don't know how to convert scalar number to float

By the way, if I avoid to perform the logarithm and do a plot like

pylab.plot(rho, entropy)

it works!

Any idea?
