如何将EasyOROR用于多处理？

Question

我试图在Python上使用EasyORCOR的图像上阅读文本，并且我想单独运行它，以免阻止代码的其他部分。但是，当我在多处理循环中调用该函数时，我会遇到一个通知的错误。这是代码的示例。

import multiprocessing as mp
import easyocr
import cv2

def ocr_test(q, reader):
    while not q.empty():
        q.get()
        img = cv2.imread('unknown.png')
        result = reader.readtext(img)


if __name__ == '__main__':
    q = mp.Queue()
    reader = easyocr.Reader(['en'])

    p = mp.Process(target=ocr_test, args=(q,reader))
    p.start()
    q.put('start')
    p.join()

这是我遇到的错误。

NotImplementedError: Could not run 'aten::empty.memory_format' with arguments from the 'QuantizedCPU' backend. This could be because the operator doesn't exist for this backend, or was omitted during the selective/custom build process (if using custom build).

有没有办法解决这个问题？
