Numpy 在运行 Python 文件时出现内存错误

Question

I'm trying to run a Python file, but every time it gives me this error. What could be the cause of this error and a possible solution? I'm using the latest version of numpy-1.17.0

numpy.core._exceptions.MemoryError: Unable to allocate array with shape 
(129941, 400, 16) and data type int32

Answer 1

I think your array is too big. int32 is 32 bits so 4 bytes and 4*129941*400*16 = 3326489600 bytes = 3.3264896 Gigabytes .

Answer 2

This is likely due to your system's overcommit handling mode .
In the default mode, 0 ,
You can check it using

$ cat /proc/sys/vm/overcommit_memory

You have to set it 1 ,using

$ echo 1 | sudo tee /proc/sys/vm/overcommit_memory
