ctc_loss.cpp:509:10: fatal error: 'ctc.h' file not found

[eravallirao]

I am getting the above warning while running "make"

After that while running this command python3 setup.py build_ext --inplace I am getting the below error.

Can you please help me with this

[Bartzi]

did you run make install after building warp_ctc? Did you make sure that Cython is able to find the header files of warp_ctc.

[eravallirao]

I am getting this while running make install

[eravallirao]

I tried giving "sudo"

[eravallirao]

Did you make sure that Cython is able to find the header files of warp_ctc?
How can we check this? I am little bit new to this, please don't mind if I am asking for basics.

[Bartzi]

if your CMAKE_INSTALL_PREFIX is set to /usr/local. Cython should be able to find your files, once you did run make install successfully.

[eravallirao]

I followed the path you asked to, still I am getting the error of ctc.h not found

[eravallirao]

Do you have any docker setup available

[Bartzi]

did you check that ctc.h is in /usr/local/include?
Unfortunately, I can not provide a docker image at the moment.

[eravallirao]

Sorry for late reply.
Yeah I did check, It was not there. I copied the ctc.h file and copied into the path you specified and ran it. I am getting other error

[Bartzi]

It seems that the linker can not find the library. Where is your compiled library stored on your pc? Is that path in your environment variable LD_LIBRARY_PATH?

[eravallirao]

Sorry can you please tell me about the compiled library? FYI I don't have CUDA. I am running it on MAC

[eravallirao]

sukshis-MacBook-Air-2:ctc Puru$ echo $LD_LIBRARY_PATH
/Users/sukshi/torch/install/lib:

[Bartzi]

the compiler creates a .so file once you are done with compiling the warpctc library. That is the file I'm talking about. If you place this file in /Users/sukshi/torch/install/lib the compiler, compiling the python extension, might find it.

[eravallirao]

Are you talking about the same .so file which is in that directory?

[Bartzi]

No, I'm talking about a file that sshould be named libwarpctc.so or something like that. I see that you have a libwarpctc.dylib file. This might be a mac equivalent of a .so file but I don't know anything about macs and I can not help you with that. In the Linux world you'll need a .so file for the linker but how that stuff works on mac (if it is different at all) I really don't know.
