Thanks Chris, If this got fixed towards numarray version 1.5.1 it looks like it is now on both Linux and Mac different(!) from the numpy result I got on Window !! On Linux I get: >>> import numpy as N >>> N.__version__ '0.9.9.2823' >>> bbb=N.zeros((2,3,3), N.float32) >>> bbb[0,:,:]=1 >>> bbb[1,:,:]=2 >>> bbb [[[ 1. 1. 1.] [ 1. 1. 1.] [ 1. 1. 1.]]
[[ 2. 2. 2.] [ 2. 2. 2.] [ 2. 2. 2.]]] >>> ccc=N.transpose(bbb,(1,0,2)) >>> d=N.array([[1,0],[0,1]]) >>> d [[1 0] [0 1]] >>> N.dot(d,ccc) Traceback (most recent call last): File "<input>", line 1, in ? TypeError: array cannot be safely cast to required type >>> dd=d.astype(N.float32) >>> N.dot(dd,ccc) [[[ 1. 1. 1.] [ 1. 1. 1.] [ 1. 1. 1.]] [[ 2. 2. 2.] [ 2. 2. 2.] [ 2. 2. 2.]]] >>> The TypeError looks like a numpy bug !
