TesseractError：'打开数据文件\\ Program Filesx86\\ Tesseract-OCR \\ eng.traineddata时出错

如何解决TesseractError：'打开数据文件\\ Program Filesx86\\ Tesseract-OCR \\ eng.traineddata时出错

我正在尝试在Jupyter Notebook上使用pytesseract。

Windows 10 x64 以管理权限运行Jupyter Notebook（Anaconda3，Python 3.8.3）

包含TIFF文件的工作目录位于其他驱动器（Z :)中 当我运行以下代码时：

pytesseract.pytesseract.tesseract_cmd = 'C:/Program Files (x86)/Tesseract-OCR/tesseract.exe'
img = cv2.imread('1.png')
img = cv2.cvtColor(img,cv2.COLOR_BGR2RGB)

hImg,wImg,_ = img.shape
conf = r'--oem 3 --psm 6 outputbase digits'
boxes = pytesseract.image_to_data(img,config=conf)
for a,b in enumerate(boxes.splitlines()):
        print(b)
        if a!=0:
            b = b.split()
            if len(b)==12:
                x,y,w,h = int(b[6]),int(b[7]),int(b[8]),int(b[9])
                cv2.putText(img,b[11],(x,y-5),cv2.FONT_HERSHEY_SIMPLEX,1,(50,50,255),2)
                cv2.rectangle(img,y),(x+w,y+h),2)

cv2.imshow('Img',img)
cv2.waitKey(0)

我收到以下错误：

我想通过环境变量而不是通过在pytesseract.image_to_data（）中设置配置变量之类的代码来解决此问题。
