Tesseract DLL failed about python-tesseract HOT 28 CLOSED

Correct me if I am wrong. 

Neither Lepontica Nor Tesseract has x64 windows version. So is python-tesseract

You should consider installing 32bit version of python rather than 64bit in 
your already 64bit OS. 

I have this issue with 32bit version of python.  Python 2.7.3 (default, Apr 10 
2012, 23:31:26) [MSC v.1500 32 bit (Intel)] on win32

I am able to run python-tesseract 0.7, but I get the ImportError: DLL load 
failed for _tesseract when I try to use python-tesseract 0.7.4.

I would like to upgrade to use the new CvImage to OCR without writing to disk.

If u are using 64bit OS installed with 32bit Python, please try help me testing 
the following file:

http://python-tesseract.googlecode.com/files/python-tesseract-0.7.4-1.win32-py2.
7.exe

I still get the error with the test build.

Windows 7 64bit
Python 2.7.3 32bit

Then, do me a favour. I need to find out what dlls are missing.
1) cd C:\Python27\Lib\site-packages
look for a file called _tesseract.pyd
2) download http://www.dependencywalker.com/
3) use dependency walker to determine what dlls a re missing.

Looks like there might be a few problems.

1.  opencv_core240.dll is missing a dependency for tbb.dll
2.  there are some missing files for tesseract (tesseract-dll.exe, 
tesseract302.exp and tesseract302.lib)
3.  some of the files are not in the correct directory from the installer 
(liblept168.dll, libtesseract302.dll and opencv_core240.dll)

0.7.4-1 installs the following from the python-tesseract-wininst.log:
200 File Copy: C:\Python27\liblept168.dll

Pls confirm whether moving the three dlls into site-packages will fix the 
problem

[deleted comment]

It is not fixed unless I add tbb.dll.  I tested with tbb.dll that was ia32 vc8. 

then 4 files to site-packages?

Yes, those 4 files to site-packages fixes it.

Pls help test again
http://python-tesseract.googlecode.com/files/python-tesseract-0.7.4-2.win32-py2.
7.exe

[deleted comment]

That works for me.

Thanks for the quick response!

By the way, it should not be deemed as a proper way to do it. Inside 
site-packages, there are no any dll files. 


I guess the root cause is that you didn't include C:\python27 into your %PATH%

I never tested with the dlls still in the C:\python27 directory after I added 
the tdd.dll.  I just did and it works.

Which means the only problem for me was the missing tdd.dll and not the 
location of the other dlls.

Are u suggesting to me that I should put back all 4 dlls to c:\python27?

Sigh.... I need someone to buy me a coffee 

Have a nice day

I think it is whatever you prefer.  It works both ways for me now that I have 
tdd.dll.

Pls help me check again.

7.exe

Many thanks

Works perfectly

both example 1 and example 2 on the frontpage?

Yes, both examples work for me.

Thanks again

I am seeing this work if importing directly from within the python console or 
when running as a script, but I'm receiving the following error when I attempt 
to run an executable built with py2exe 0.6.10:

  File "zipextimporter.pyo", line 82, in load_module
  File "tesseract.pyo", line 26, in <module>
  File "tesseract.pyo", line 18, in swig_import_helper
  File "zipextimporter.pyo", line 98, in load_module
ImportError: MemoryLoadLibrary failed loading _tesseract.pyd


I'm using the most recent build of python-tesseract and python 2.7.2 in Windows 
7. Any ideas?
