Hi,
Running the test suite for one of our libraries, there seems to have
been a recent breakage of the behavior of dtype hashing.
This script:
import numpy as np
data0 = np.arange(10)
data1 = data0 - 10
dt0 = data0.dtype
dt1 = data1.dtype
assert dt0 == dt1 # always passes
assert hash(dt0) ==
Dear sir,
Can we do multiple linear regression(MLR) in python is there any
inbuilt function for MLR

Hello,
I have a dictionary with structured arrays, keyed by integers 0...n.
There are no other keys in the dictionary.
What is the most efficient way to convert the dictionary of arrays to
a single array?
All the arrays have the same 'headings' and width, but different lengths.
Is there

Yes, you can use np.linalg.lstsq [1] for this.
Here's a quick example:

Hi!
This little snippet of code tricked me (in a more convoluted form). The *=
operator does not change the datatype of the left hand side array. Is this
intentional? It did fool me and throw my results quite a bit off. I always
assumed that 'a *= b' means exactly the same as 'a = a * b' but

IIRC, a few years back there was a long thread on the list about unbiased vs
biased estimates of std and ddof may have been added then...

In that case, would you agree that it is a bug for
assert_array_almost_equal to use repr() to display the arrays, since it
is printing identical values and saying they are different? Or is there
also a reason to do that?
It should probably use np.array_repr(x, precision=16)
