如何删除“使用Leptonica的Tesseract开源OCR引擎v3.02”消息

When I use pytesser (the image processing lib with tesseract-ocr for python) and run:

当我使用pytesser (python中带有tesserac -ocr的图像处理库)并运行时:

image= Image.open(ImagePath)
text = image_to_string(image)
print text

as a result I get the text, as well as this line from tesseract:

结果，我得到了文本，以及来自tesseract的这一行:

Tesseract Open Source OCR Engine v3.02 with Leptonica

I think this line runs when the image_to_string function is run.

我认为这一行在运行image_to_string函数时运行。

This really clogs up the output printed in the console. And is really annoying. Does anyone know how to get rid of it? Maybe a line in python or something?

这确实会阻塞控制台中打印的输出。,真的很烦人。有人知道怎么处理吗?可能是python里的一条线还是什么?

4 个解决方案

#1

What you do is open pytesser.py in the main pytesser folder and change this function:

你要做的是打开pytesser。py在pytesser主文件夹中并更改此函数:

def call_tesseract(input_filename, output_filename):
    """Calls external tesseract.exe on input file (restrictions on types),
    outputting output_filename+'txt'"""
    args = [tesseract_exe_name, input_filename, output_filename]
    proc = subprocess.Popen(args)
    retcode = proc.wait()
    if retcode!=0:
        errors.check_for_errors()

来

def call_tesseract(input_filename, output_filename):
    """Calls external tesseract.exe on input file (restrictions on types),
    outputting output_filename+'txt'"""
    devnull = open(os.devnull, 'w')
    args = [tesseract_exe_name, input_filename, output_filename]
    proc = subprocess.Popen(args, stderr=devnull)
    retcode = proc.wait()
    if retcode!=0:
        errors.check_for_errors()

and also add import os to the top of the file.

并将导入操作系统添加到文件的顶部。

Frist create a config file

创建一个配置文件。

cat <<CNF >>/usr/share/tessdata/tessconfigs/nobanner
debug_file /dev/null
CNF

Note that your tessconfigs could be somewhere else, likes /usr/local/share/tessdata/tessconfigs.

注意，您的tessconfigs可能在其他地方，比如/usr/local/share/tessdata/tessconfigs。

Then use 'nobanner' on the command line

然后在命令行上使用“nobanner”。

tesseract infile.png outprefix -l eng nobanner

#3

only the code below got success:

只有下面的代码成功了:

tesseract infile.png outprefix 1>/dev/null 2>&1

#4

You can try to redirect it to a log file by setting the debug_file parameter.

可以通过设置debug_file参数将其重定向到日志文件。
