Rows are generated in the same order I'd like to have them in the final matrix. csr matrix is preferable over lil matrix, but I assume the latter will be easier to build in the scenario I'm describing. Assuming row_gen is a generator yielding numpy.array rows, the following code works as expected. def row_gen(): yield numpy.array([1, 2, 3]) yield numpy.array([1, 0, 1]) yield numpy.array([1, 0, 0])

I have a GWT client where I want the user to select a file using the FileUpload control and send it to the web service via HTTP stream. The file upload control contains a method to get the file path of the selected file. How can I then get that file and convert it to a byte array? I'm open to suggestions on how to get the file to my web service, not quite sure the Byte array will work... 回答1: If you want to convert the file in GWT, meaning in the browser. It's not possible to do in the

I have 2 arrays where the size of long is 8 and the size of char is 1 long x[2] = {0x012345,0xFEDC}; char c[12] = {'a','b','c','d','e','f','g','h','0','1','2','3'}; And I was wondering how these values would be stored in the different Endian architectures if we consider x starting at memory address 0x100 and c starting at memory address 0x200 . I thought that the Big Endian address would be {01,23,45,FE,DC}
