My use case is simple, i have performed some kind of operation on image and the resulting feature vector is a numpy object of shape rowX1000(what i mean to say is that the row number can be variable but column number is always 1000)
I want to store this numpy array in mysql. No kind of operation is to be performed on this array. The query will be simple given a image name return the whole feature vector. so is there any way in which the array can be stored (something like a magic container which encapsulates the array and then put it on the table and on retrieval it retrieves the magic container and pops out the array)
I want to do this in python. If possible support with a short code snippit of how to put the data in the mysql database.
A NumPy array can be specified to be stored in row-major format, using the keyword argument order='C' , and the column-major format, using the keyword argument order='F' , when the array is created or reshaped. The default format is row-major.
NumPy arrays are typed arrays of fixed size. Python lists are heterogeneous and thus elements of a list may contain any object type, while NumPy arrays are homogenous and can contain object of only one type.
You can save your NumPy arrays to CSV files using the savetxt() function. This function takes a filename and array as arguments and saves the array into CSV format. You must also specify the delimiter; this is the character used to separate each variable in the file, most commonly a comma.
NumPy doesn't natively support GPU s. However, there are tools and libraries to run NumPy on GPU s. Numba is a Python compiler that can compile Python code to run on multicore CPUs and CUDA-enabled GPU s.
You could use ndarray.dumps() to pickle it to a string then write it to a BLOB field? Recover it using numpy.loads()
