jingyimei opened a new pull request #401: DL: fix default_buffer_size calculation URL: https://github.com/apache/madlib/pull/401 JIRA: MADLIB-1340 In buffer size calculator, we assumed the array to be packed is one dimention, and use the array_upper(x, 1) to get the length of the array. In DL input data preprocessor, we passed the first element in array_ndims as the length, which is not right because the array can be multi-dimentional. This caused default_buffer_size_calculator returns a bigger buffer size than it supposed to have and rows get too big and crashes database. Instead, we should use product of all the elements from array_ndims to represent the actual length of the array. For example, if array_ndims returns [32,32,3], we should pass 32*32*3 instead of 32. This commit fixes this issue by passing the right length to defualt buffer calculator.
