我可以让 pytesseract 命令在抛出错误的 pycharm 中正常工作吗

Question

我正在定义一个功能，它将图像转换为灰度（位黑白色），然后将其传递给：

text = pytesseract.image_to_string(Image.open(gray_scale_image))

然后我打印我收到的文本，但它抛出错误：

Traceback (most recent call last):

  File "C:\Users\HP\PycharmProjects\nayaproject\venv\lib\site-packages\PIL\Image.py", line 2613, in open

fp.seek(0)

AttributeError: 'numpy.ndarray' object has no attribute 'seek'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

  File "C:/Users/HP/PycharmProjects/nayaproject/new.py", line 17, in <module>

text = pytesseract.image_to_string(Image.open(g))

fp = io.BytesIO(fp.read())

AttributeError: 'numpy.ndarray' object has no attribute 'read'

而不是 Image.open(grayscale)，当我使用 Image.fromarray(grayscale) 我得到这些错误：

Traceback (most recent call last):

我正在研究 PyCharm，并且我已经为这个项目安装了 Pillow、numpy、opencv-python、pip 和 pytesseract。

因为我猜gray_scale_image是从 OpenCV 输出的，因此是 numpy 数组，如错误所示AttributeError: 'numpy.ndarray' object has no attribute 'read'您需要将数组转换为 PIL 对象。根据我自己的经验，我建议您将 numpy 数组自动转换为 np.uint8，因为 PIL 使用 8 位，并且您通常不了解 OpenCV 算法的内容。text = pytesseract.image_to_string(Image.fromarray(gray_scale_image.astype(np.uint8)))如果上述方法不起作用，则您绝对不会传递任何形式的 Image 数组。尝试输入这些以找到争论的特征：print(type(gray_scale_image))print(gray_scale_image.shape)在这将解决您的第一个问题之后，将会出现您尚不知道的新问题。您需要将路径添加到您的 pytesseractpytesseract.pytesseract.TesseractNotFoundError: tesseract is not installed or it's not in your path解决方案是在开头添加您的路径pytesseract.pytesseract.tesseract_cmd = 'C:/Program Files (x86)/Tesseract-OCR/tesseract'TESSDATA_PREFIX = 'C:/Program Files (x86)/Tesseract-OCR'
