That actually happened to me because I was using the wrong Python version (I had both 3.5 and 3.6).

You need to install sudo apt-get install python3.5-dev for your Python version (this example is for 3.5, just check which version you are trying to build against).

Please, let me know if this works

Odd..i assumed Ubuntu as python-dev by default

Can you try these solutions:

sudo apt-get install python3-dev

not working, still same error

Then i can't answer unless you provide your whole config as the issue template indicated (closed temporarily until the config is added)

sorry, i give up debugging and try reinstall my ubuntu OS, then install all from beginning

seni04 on 21 Jan 2019

That should definitively work, as long as you run sudo apt-get install python-dev python3-dev (I would add this to the doc soon)

I can confirm the same problem with Ubuntu 16.04. When I locate the Python.h with:
locate Python.h

I receive:

/usr/include/python2.7/Python.h
/usr/include/python3.5m/Python.h

So, the system contains the necessary header files. I am working on this. If I can figure out what the problem is, I will add it to this thread.

Update 1: Reinstalling the dependencies _did not_ solve the problem.

you can manually add python flags in cmake-gui, if you enable "Advance" mode:

search for CMAKE_CXX_FLAGS and add " -I/usr/include/python2.7 -lpython2.7 "

I can confirm this solution works.

i am newer，i do not where CMAKE_CXX_FLAGS is，can you help me？

Go to your build directory

cd openpose/build
cmake ..

Note it’s .. and not a . If you get an error, I think it will prompt you to install something like curses.

This should activate the cmake parameters menu, look at the bottom screen for advanced ( I think it’s t ), it will flesh out more parameters. Move the cursor to the line for the parameter to change, press Enter to change to whatever you want. Then press c to configure and g to generate. You can then do a make -j4 ( or how ever number of cpu you have )

i got the same problem when using python3.6, it's not work with "sudo apt-get install python-dev python3-dev"; but it works after remove python3.6,

Can you please give an example what exactly to modify in the file and how?
I am using Ubuntu 18.04

None of the solutions worked for me except this one:

search for CMAKE_CXX_FLAGS and add " -I/usr/include/python2.7 -lpython2.7 "

I have worked with openpose previously on the same OS but this error popped up for the first time now. Not able to understand what changed.
