python - How to check if GPU memory is available using PyOpenCL -


i know if there way check how gpu memory available before function uses it. have code uses 1.5 gb of gpu memory or more, , if else using gpu when program wants use it, memoryerror exception or similar.

i implement sort of code can check see if gpu has enough memory available, , if does, go ahead , run, if not, wait until available.

(preferably, check before trying use gpu rather using try-except loop , retrying if fails)

i checked pyopencl documentation see if there relevant under device_info, couldn't find actual descriptions.

this not possible, , limitation of opencl, not pyopencl. see here.

on nvidia devices, can use nvidia-ml-py. can this:

from pynvml import * nvmlinit() in range(nvmldevicegetcount()):     handle = nvmldevicegethandlebyindex(i)     meminfo = nvmldevicegetmemoryinfo(handle)     print("%s: %0.1f mb free, %0.1f mb used, %0.1f mb total" % (         nvmldevicegetname(handle),         meminfo.free/1024.**2, meminfo.used/1024.**2, meminfo.total/1024.**2)) nvmlshutdown()

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
