此問題與previous question I asked有關,它看起來像一個簡單的問題,但我很難找到有關多處理主題的有用信息或教程。聯合輸出多處理python
我的問題是,我想將生成的數據組合成一個大數組,然後將其存儲在我的hdf文件中。
def Simulation(i, output):
# make a simulation which outputs it resutlts in A. with shape 4000,3
A = np.array([4000,3])
output.put(A)
def handle_output(output):
hdf = pt.openFile('simulation.h5',mode='w')
hdf.createGroup('/','data')
# Here the output should be joined somehow.
# I would like to get it in the shape [4000,3,10]
output.get()
hdf.createArray('/data','array',A)
hdf.close()
if __name__ == '__main__':
output = mp.Queue()
jobs = []
proc = mp.Process(target=handle_output, args=(output,))
proc.start()
for i in range(10):
p = mp.Process(target=Simulation, args=(i, output))
jobs.append(p)
p.start()
for p in jobs:
p.join()
output.put(None)
proc.join()
簡單有效! – user2143958 2013-04-08 15:09:47
