RE: [NUMPY] ValueError: total size of new array must be unchanged just on Windows
Redirecting to his question to the list. I need of a matrix, not of an array. But is this error due to a numpy bug? I am not an expert on NumPy/SciPy, but I do not believe matrixes are allowed to be 3 dimensional. Google only produced results of 3 dimensional arrays.

Nobody can help me? 2011/10/12 Paolo Zaffino zaffin...@gmail.com I wrote a function thaht works on a 3D matrix. As first thing I have an array and I want reshape it into a 3D matrix (for further manipulations). For this reason I wrote in a row: matrix=matrix.reshape(a, b, c).T It work fine on GNU/Linux and Mac OS but not on Windows. In Windows I get this error: matrix=matrix.reshape(a, b, c).T ValueError: total size of new array must be unchanged Thank you. 2011/10/11 David Robinow drobi...@gmail.com 2011/10/11 Paolo Zaffino zaffin...@gmail.com: Nobody can help me?

Print them in the ones which work (GNU/Linux and Mac OS) and the one which doesn't (Windows). Do they print the same values? Do not assume that they are the same.

The reshape()d array must have the same total number of elements as the original array. If it works on one platform and not on another, that indicates that either matrix has a different shape on different platforms, or a*b*c is different on different platforms. As no-one here (except you) has any idea how matrix, a, b and c are getting their values, it's impossible for us to say why they're getting different values on different platforms. -- http://mail.python.org/mailman/listinfo/python-list
