[Tutor] HOW TO DOWNGRADE NUMPY

[SATYABRATA DATTA]

I am facing this issue

*AttributeError: 'float' object has no attribute 'log'*

y = np.sum(n*m2*m2* (np.log(np.abs(m2/self.renormScaleSq) + 1e-100)
*TypeError: loop of ufunc does not support argument 0 of type float
which has no callable log method*

How to downgrade numpy, since all mentioned ways of doing it on stack
exchange are not working. Tese errors are not there in previous
versions of numpy(like on 1.15.4)
