How should this problem be solved?

In the process of using your code, I encountered a small problem, that is, only a part of the text can be recognized. I guess the recognition threshold needs to be adjusted. Because of the time constraint, I didn't see your code well, so I want to ask you how to adjust the threshold value!

Thank you for sharing your code.

When I run your code for test image, I get the result here.

It seems to be much worse than your result. But I have no idea why that happens. Can you help me solve this problem?

Dear Azmio Zen Please solve this error.

Thanks for sharing. When I run the code, there'is some errors that I have no idea to work out, " File "D:\Program Files\Anaconda3\envs\test_py2\lib\site-packages\pytesseract\pytesseract.py", line 116, in run_tesseract
raise TesseractError(status_code, get_errors(error_string))
pytesseract.pytesseract.TesseractError: (1, u'Error opening data file ./tessdata/eng.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory. Failed loading language 'eng' Tesseract couldn't load any languages! Could not initialize tesseract.')"
Would you please tell me something that I need to check out?
非常感谢，尝试了先使用短的代码来实验，还是会报同样的error，实验和error如下：

from PIL import Image
import pytesseract
imageObject=Image.open('test.jpg')
print (imageObject)

print (pytesseract.image_to_string(imageObject))

I've executed this command python text_detect.py -i images/scenetext01.jpg , but got this error
