Use CI to test and release detectron2 for Windows #1712

Open shlpu opened 4 years ago

shlpu commented 4 years ago

Are you willing to release Pre-Built Detectron2 For Windows? Thanks a lot.

ppwwyyxx commented 4 years ago

We don't have such plans, but would appreciate it if anyone is willing to help us set up the CI on windows.

sarthakforwet commented 4 years ago

Hey @shlpu nice thought! @ppwwyyxx I wanna work on this issue can you please tell me what I need to know related to the issue before start working on it. Thanks.

ppwwyyxx commented 4 years ago

We use CircleCI at https://github.com/facebookresearch/detectron2/blob/master/.circleci/config.yml. It provides windows support so it can be configured with automated scripts to install dependencies, build detectron2 and run tests for every commit, on windows. https://github.com/pytorch/vision/blob/master/.circleci/config.yml can be used as a reference.

@ppwwyyxx I am successful in installing dependencies with windows executor but quite unable to find out how should I install detectron2 on windows.

Here's my sample config file (only for experiments not the complete ready code) - 

version: 2.1

windows-cpu: &windows_cpu

      resource_class: windows.medium

        python -m venv ~/venv
        echo ". ~/venv/bin/activate" >> $BASH_ENV
        . ~/venv/bin/activate

        pip install --upgrade pip

        python setup.py build develop

I am unable to build detectron2 this way. I've found a windows build for detectron2, can we build it like that or any other way? Thanks

sarthakforwet commented 4 years ago

@ppwwyyxx, The only place where I am getting stuck is the installation of pycocotools on windows. As this package is necessary for the installation of detectron2, we need to find a way to install pycocotools on windows.

Related issue: https://github.com/cocodataset/cocoapi/issues/169

PS: I have tried the solution provided in the aforementioned issue but on executing any of the following commands, it exits out with an error.

soad89 commented 4 years ago

Hi. @sarthakforwet what error you get? I am ussualy able to install it on Win10, with some modifications in setup. I can try to assist.

sarthakforwet commented 4 years ago

Hey @soad89 thanks for the support! So basically I tried the following-

and then tried the below approaches to build detectron2:

$ pip install -U --progress-bar off -e .[dev]

This gave the following error-

As can be seen, it errored out at building pycocotools.

After that I tried the following command (in a new environment with aforementioned deps installed).

$ python setup.py build develop

This gave me the following error:

Then I installed deps specified in conansherry's repo (in a new environment)

$ python -m pip install 'git+https://github.com/facebookresearch/fvcore'
$ python -m pip install opencv-python pytest-xdist
$ pip install torch==1.6.0+cpu torchvision==0.7.0+cpu -f https://download.pytorch.org/whl/torch_stable.html
$ pip install cython
$ pip install git+https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI

and then ran the following command.

$ cd detectron2
$ python setup.py build develop

It gave me the same error mentioned above with directory as original detectron2 repo and gives the following error with directory as conansherry's detectron2 repo:

PS: I also tried to install latest versions of torch and torchvision but they also errored out at building of pycocotools. Even if I would be able to build from conansherry's repo, the version of detectron2 would still be 0.1.

ppwwyyxx commented 4 years ago

The pycocotools package on PyPI is built from https://github.com/ppwwyyxx/cocoapi. If there is a simple fix to make it support windows, feel free to send a PR there.

F:\Code\detectron2\detectron2\layers\csrc\cocoeval\cocoeval.cpp(483): error C3861: 'localtime_r': identifier not found

Our code is using a time function that's not available on windows. It should be replaced by something else.

Can you please guide me how can I understand the underlying code and what should be prerequisite for it so that I can work over it. Thanks!

soad89 commented 4 years ago

Hi Guys. So I had a look on https://github.com/ppwwyyxx/cocoapi

On Win10 in my case I have to edit following section in https://github.com/ppwwyyxx/cocoapi/blob/master/PythonAPI/setup.py

ext_modules = [ Extension( 'pycocotools._mask', sources=['./common/maskApi.c', 'pycocotools/_mask.pyx'], include_dirs = [np.get_include(), './common'], extra_compile_args=['-Wno-cpp', '-Wno-unused-function', '-std=c99'], ) ]

to:

ext_modules = [ Extension( 'pycocotools._mask', sources=['../common/maskApi.c', 'pycocotools/_mask.pyx'], include_dirs = [np.get_include(), '../common/'], extra_compile_args=[] ) ]

Please try it if it works also for you. If so one can distinguish in setup by os.name and modify ext_modulesto meet Win10.

sarthakforwet commented 4 years ago

Thanks @soad89! I have changed the code as you suggested and used the platform module to differentiate between Windows and other OS.
