download binary from <a href="https://github.com/UB-Mannheim/tesseract/wiki" rel="noreferrer">https://github.com/UB-Mannheim/tesseract/wiki</a>. then add <code>pytesseract.pytesseract.tesseract_cmd = 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract.exe'</code> to your script.

On a Mac, you can just install using homebrew:

I faced the same problem. I hope you have installed from <a href="https://github.com/UB-Mannheim/tesseract/wiki" rel="nofollow noreferrer">here</a> and have also done <code>pip install pytesseract</code>.

If everything is fine you should see that the path <code>C:\Program Files (x86)\Tesseract-OCR where tesseract.exe</code> is available.

Adding Path variable did not helped me, I actually added new variable with name <code>tesseract</code> in environment variables with a value of <code>C:\Program Files (x86)\Tesseract-OCR\tesseract.exe</code>.

Typing <code>tesseract</code> in the command line should now work as expected by giving you usage informations. You can now use <code>pytesseract</code> as such (don't forget to restart your python kernel before running this!): 

<pre><code>import pytesseract
from PIL import Image

value=Image.open("text_image.png")
text = pytesseract.image_to_string(value, config='') 
print("text present in images:",text)
</code></pre>

Most likely you have different versions of Python installed, ensure that the installed Tesseract is on the same Python version.

Ensure that these two are the same.

blocks|key|4265887|text|当当前目录位于与tesseract安装位置不同的驱动器上时，在windows下(至少在tesseract版本3.05中)会发生这种情况。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4265888|tesseract中的某些内容希望数据文件位于\Program+files中...(而不是C:\Program+Files+)。因此，如果您不在与tesseract相同的驱动器号上，它将失败。如果我们可以在执行tesseract之前将驱动器(仅在windows下)临时更改为tesseract安装驱动器，然后在执行tesseract之后再更改回来，那就太好了。在您的例子中:您可以将yourmodule_python.py复制到"C/Program+Files+(x86)/Tesseract-OCR/“并运行！|4265889|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

This occurs under windows (at least in tesseract version 3.05) when the current directory is on a different drive from where tesseract is installed.

Something in tesseract is expecting data files to be in \Program Files... (rather than C:\Program Files, say). So if you're not on the same drive letter as tesseract, it will fail. It would be great if we could work around it by temporarily changing drives (under windows only) to the tesseract installation drive before executing tesseract, and changing back after.
Example in your case: You can copy yourmodule_python.py to "C/Program Files (x86)/Tesseract-OCR/" and RUN!
