I've checked it a bit more and there is new problem
with debug packages:
$ python3.6-dbg -c 'import pyopencl'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/pyopencl/__init__.py", line 37,
in <module>
    import pyopencl._cl as _cl
ImportError: /usr/lib/python3/dist-packages/pyopencl/_cl.cpython-36dm-
x86_64-linux-gnu.so: undefined symbol: PyModule_Create2

$ python3.7-dbg -c 'import pyopencl'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/pyopencl/__init__.py", line 37,
in <module>
    import pyopencl._cl as _cl
ImportError: /usr/lib/python3/dist-packages/pyopencl/_cl.cpython-37dm-
x86_64-linux-gnu.so: undefined symbol: PyModule_Create2

$ python3.7 -c 'import pyopencl'

$ python-dbg -c 'import pyopencl'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/pyopencl/__init__.py", line 37,
in <module>
    import pyopencl._cl as _cl
ImportError: /usr/lib/python2.7/dist-packages/pyopencl/_cl.x86_64-linux-
gnu_d.so: undefined symbol: Py_InitModule4_64

So PyOpenCL works with Python3.7 right now, but debug symbols
do not work at all (neither for Python 3, nor for Python 2.7).
It might be related to move to pybind.
At the same time I found some information suggesting that 
debug packages need to be compiled differently.

It's either deliberate Python behavior
https://bugs.python.org/issue5735
"Python compiled with --with-pydebug throws an ImportError when trying
to
import modules compiled without --with-pydebug, as it should"

or some strange gcc error
https://riverbankcomputing.com/pipermail/pyqt/2014-July/034561.html
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=755767

I'll need to investigate.
If somebody has any idea, please let me know.
