Build boost-numpy with boost-python #5732

Open palotasb-conti opened 5 years ago

palotasb-conti commented 5 years ago

Hi, I'm using boost-python with the builtin numpy support enabled. Boost build decides whether to build the boost-numpy library as part of the boost-python library based on whether executing python -c "import sys; sys.stderr = sys.stdout; import numpy; print(numpy.get_include())" succeeds or not. See https://github.com/boostorg/build/blob/e22a75c8fd83f0e52adea4f48ef5f9fbbdf5b72c/src/tools/python.jam#L838-L857

Is there a way using Vcpkg to (1) rely on the Python installed by Vcpkg and (2) force boost to build the boost-numpy library as well?

I have tried the following script:

REM file: build.bat

REM pybind11 only used to install Python.exe in vcpkg\downloads\tools\python\python3\python.exe
.\vcpkg\vcpkg.exe install pybind11

REM install pip3.exe. See: https://pip.pypa.io/en/stable/installing/
.\vcpkg\downloads\tools\python\python3\python.exe "../path/to/get-pip.py"

REM install numpy
.\vcpkg\downloads\tools\python\python3\Scripts\pip3.exe install numpy==1.16.2

REM verify that if boost build used the Vcpkg Python installation it would see numpy
.\vcpkg\downloads\tools\python\python3\python.exe -c "import sys; sys.stderr = sys.stdout; import numpy; print(numpy.get_include())"
REM prints correct path to .\vcpkg\downloads\tools\python\python3\lib\site-packages\numpy\core\include

set PATH=\full\path\to\vcpkg\downloads\tools\python\python3;%PATH%

REM try to build boost python
.\vcpkg\vcpkg.exe install boost-python

The expected result is that boost-ptython gets built with boostnumpy.

Instead, it is not built and the log say this:

Any ideas how to solve this, or any willingness to support this use case with Vcpkg?

I have tried the following script:

well it's written right there --- "../path/to/get-pip.py"

by mistake the same

palotasb-conti commented 5 years ago

@Voskrese What I imply here is that I have separately downloaded the get-pip.py script and I'm invoking it. This part works; it builds the vcpkg\downloads\tools\python\python3\Scripts\pip3.exe used in the next command. ../path/to/get-pip.py and /path/to/vcpkg do not necessarily refer to the same path, it is just a placeholder and it is not causing the issue as far as I see.

by mistake the same

notice: [python-cfg] Configuring python... notice: [python-cfg] user-specified version: "3.6"

I do not understand what you are saying in your comment. Can you please explain it in simple words?

The only thing I see here is that the Python.exe under Vcpkg (and used in the script) is version 3.5, not 3.6. That might be the reason boost-build is not picking it up while building boost-python, but I'm not sure (I wasn't able to verify this).

then the reason is this

Yienschwen commented 5 years ago

I'm not an expert in vcpkg or b2, so some of the technical details may be incorrect.

The situation is:

However, python is actually searched by b2 of boost-build instead of CMake.

The "call stack" of boost-python build is:

cmake: ports/boost-python/portfile.cmake
  cmake: installed/.../shared/boost-build/boost-modular-build.cmake
    b2: ...

And python related paths are formatted into user-config.jam copy of build variant of boost-python in its buildtree, where the original user-config.jam originates from installed/.../shared/boost-build/user-config.jam.

b2 uses the information in the copied user-config.jam to search for python executable in the way detailed in installed/.../tools/boost-build/src/tools/python.jam, that searches for python registry if the cmd-or-prefix field in user-config.jam is empty.

So the brute-force and dirty solution is to fill the cmd-or-prefix field of installed/.../shared/boost-build/user-config.jam, otherwise b2 will never build boost-numpy library.

P.S., IMO, python path should have the option to be given manually by user, since user may have python installed in virtual environments or anything else, and that's user-config.jam designed for.

Hi! I have the same issue and @Yienschwen solution didn't help, it still unable to find python in the directory for numpy check.

In the same time, local boost distribution built well with numpy. Will be grateful for any help, thanks!

vlarin commented 4 years ago

So dirty workaround that worked:

  1. Open C:\vcpkg\installed\x64-windows\tools\boost-build\src\tools\python.jam
  2. At line ~838 change code to the following (just be sure to provide correct location of numpy headers): 
    #
# Discover the presence of NumPy
#
debug-message "Checking for NumPy..." ;
local full-cmd = "import sys; sys.stderr = sys.stdout; import numpy; print(numpy.get_include())" ;
local full-cmd = $(interpreter-cmd)" -c \"$(full-cmd)\"" ;
debug-message "running command '$(full-cmd)'" ;
local result = [ SHELL $(full-cmd) : strip-eol : exit-status ] ;
#if $(result[2]) = 0
#{
    .numpy = true ;
    .numpy-include = "C:/Program Files (x86)/Microsoft Visual Studio/Shared/Python37_64/lib/site-packages/numpy/core/include" ; #$(result[1]) ;
    debug-message "NumPy enabled" ;
#}
#else
#{
#    debug-message "NumPy disabled. Reason:" ;
#    debug-message "  $(full-cmd) aborted with " ;
#    debug-message "  $(result[1])" ;
#}
  3. Remove and then install again boost.python
  4. Fix will be need to done again if you reinstall boost.build

I'm not having any luck with building libboost_numpy37-vc141-mt-x64-1_72.lib I have installed in Win10 Python 3.7.4 64bit and numpy 1.16.3 vcpkg python3 is version 3.7.3, would it matter?

removed and reinstalled boost-python, and run vcpkg install boost, because boost-python remove needed to remove few more packages than just boost-python.

I have Python 3.8 on the system and vcpkg insists on installing 3.9. I need to build boost-python with numpy for 3.8 - but this fails. I tried to resolve it by changing user-config.jam (in vcpkg\buildtrees\boost-python\x64-windows-rel\user-config.jam) but this is overwritten with 3.9. Is this the incorrect way of hinting which Python to use?

tmamakov commented 3 years ago

Hello. The problem looks much more complicated. @vlarin provided a good local solution, but it is impossible to commit such changes. Building numpy requires python, but which one? vcpkg directory has at least two copies of python, third one was installed by standart installation in the most cases.

  1. Is it possible to install python by vcpkg into the system and use it everywhere?
  2. Could we use pip for vcpkg-python and install numpy before boost-python builder call?
  3. Could you publish some recomendations or instructions of using b2 for vcpkg-boost?
Grantim commented 3 years ago

There is other workaround to try.

Also note that this file will be removed if you call: vcpkg remove boost-uninstall --recurse and added again on boost installation

Wait, that one is missing aswell ... turns out there still is a port for boost-build, but boost doesn't include it...

Well apparently I'm stuck anyways as Boost 1.85 is not compatible with Numpy 2.1.1 for API changes and the fix is included with Boost 1,86, which hasn't made it to vcpkg yet...
