尝试将简单的测试图像打印为文本时出现以下错误。
我已验证我具有Pillow(PIL 1.1.7),并尝试卸载并重新安装pytesseract。文件路径是正确的,因为如果更改它们,则会收到另一个错误消息,指出找不到该文件。
我的代码:
Traceback (most recent call last):

"c:\Users\bbrown2\Desktop\PythonMaterials\python_test_tesseract.py", line
14, in <module>
print(pytesseract.image_to_string(Image.open(image)))

packages\pytesseract\pytesseract.py", line 309, in image_to_string

raise TesseractError(status_code, get_errors(error_string))
pytesseract.pytesseract.TesseractError: (2, 'Usage: python pytesseract.py
[-l lang] input_file')
我希望它能打印出图像中的文字,但我总是这样:
Route::get('/index', 'SiteController@index')->name('home');
答案 0 :(得分:2)
问题在于pytesseract只是命令行程序Tesseract的一个不错的Python包装器。
您应该将tesseract_cmd
指向实际的Tesseract二进制文件,而不是pytesseract CLI实用程序。
因此,您需要安装Tesseract。 Windows builds可用。我选择了3.05版安装程序,默认情况下安装为C:\Program Files (x86)\Tesseract-OCR\tesseract
。然后,我运行以下命令,效果很好:
from PIL import Image
import pytesseract
pytesseract.pytesseract.tesseract_cmd = (
r"C:\Program Files (x86)\Tesseract-OCR\tesseract"
)
img = r"C:\Users\cody\Desktop\ocrtest.png"
print(pytesseract.image_to_string(Image.open(img)))
测试输入:
