Hi Ralf,
Thank you so much for your answer.
I finally figured out that the problem was because Numpy 1.9 was not linked
to BLAS. I do not know why because I simply installed numpy 1.9 via the
commands:
apt-get install python3-numpy
If anybody has the same problem, you may want to take a look in

Hello All,
there seems to be a performance issue with the covariance function in numpy
1.9 and later.
Code example:
*np.cov(np.random.randn(700,37000))*
In numpy 1.8, this line of code requires 4.5755 seconds.
In numpy 1.9 and later, the same line of code requires more than 30.3709 s
execution t
