does numpy really not let you write Python stype
rho.append(float(r))
?
No. numpy arrays are not extensible in-place in general because we use view
semantics for slices and similar operations like tr

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?

A string. You probably want to convert "columns" to floats before
appending its elements to the array.
