我用 PyQt5 GUI 创建了一个用于车牌识别的 python 程序。它使用easyocr从图像中提取文本。它作为 .py 可以正常工作，但是当我将其转换为 .exe 时，easyocr 不起作用。GUI 继续正常工作。该程序的每个部分都有错误消息。所以我可以说一切都很好，除了easyocr。

Pyinstaller 命令；（我也尝试过 --onefile ，结果相同）

pyinstaller --noconfirm --onedir --windowed --add-data 
"D:/plaka_tanıma/source;source/"  
"D:/plaka_tanıma/main.py"

我创建的脚本；

class PlakaTaniyici():

    def __init__(self):
        self.__image = None
        self.__location = None
        self.__text = None
        self.__confidence = None
        self.__err_message = False
    def __resize(self):
        height, width, channel = self.__image.shape
        oran = 1
        if width > height:
            oran = 837 / width
        else:
            oran = 521 / height
        self.__image = cv2.resize(self.__image, None, fx=oran, fy=oran)

    def __plakaYeriTespit(self):
        if self.__image is not None:
            gray = cv2.cvtColor(self.__image, cv2.COLOR_BGR2GRAY)
            bfilter = cv2.bilateralFilter(gray, 11, 17, 17)
            edged = cv2.Canny(bfilter, 30, 200)
            key_points = cv2.findContours(edged.copy(), cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE)
            countours = sorted(imutils.grab_contours(key_points), key=cv2.contourArea, reverse=True)[:10]
            for countour in countours:
                approx = cv2.approxPolyDP(countour, 10, True)
                if len(approx) == 4:
                    self.__location = approx
                    break
        else:
            self.__err_message = "Gorsel islenemiyor!"

    def __plakaOku(self):
        if self.__location is not None:
            try:
                reader = easyocr.Reader(['en'])
                tl = self.__location[0][0]
                br = self.__location[2][0]
                result = reader.readtext(self.__image[tl[1]:br[1], tl[0]:br[0]])
                self.__confidence = int(result[0][-1] * 100)
                self.__text = result[0][-2]
            except:
                self.__err_message = "Plaka okunurken hata gerçekleşti."
        else:
            self.__err_message = "Plaka tespit edilemedi!"

    def __sonGorsel(self):
        if self.__location is not None:
            self.__image = cv2.rectangle(
                self.__image,
                tuple(self.__location[0][0]),
                tuple(self.__location[2][0]),
                color=(0, 255, 0),
                thickness=4,
            )

    def plakaTespit(self, image):
        self.__reset()
        self.__image = image
        self.__plakaYeriTespit()
        self.__plakaOku()
        self.__sonGorsel()
        self.__resize()
        self.__image = cv2.cvtColor(self.__image, cv2.COLOR_BGR2RGB)
        return self.__confidence, self.__text, self.__image, self.__err_message

确切地说，我收到错误消息“Plaka okunurken hata gerçekleşti。”；

def __plakaOku(self):
        if self.__location is not None:
            try:
                reader = easyocr.Reader(['en'])
                tl = self.__location[0][0]
                br = self.__location[2][0]
                result = reader.readtext(self.__image[tl[1]:br[1], tl[0]:br[0]])
                self.__confidence = int(result[0][-1] * 100)
                self.__text = result[0][-2]
            except:
                self.__err_message = "Plaka okunurken hata gerçekleşti."
        else:
            self.__err_message = "Plaka tespit edilemedi!"

self.__location 是图像上车牌的位置。所以程序找到车牌但无法读取。所以我认为这是因为easyocr。同样，它作为 .py 可以 100% 正常工作。我必须将其转换为 .exe。
