Google colab helper script

[sirramsalott]

Issue Summary

Apologies if this is the wrong place for this. I've made a script to install OpenPose on Google Colab. It's not a particularly exciting piece of programming, but I find it really useful as I don't have access to a computer which is powerful enough to run OpenPose, even in CPU mode, so the only way I can use OpenPose is to build it on a GPU-enabled Colab runtime and then run my programs there. Since I found it really useful, I presume others might also find it useful, so I'm putting it here for developers to do with as they please.

! apt update
! apt install -y cmake sudo libopencv-dev
! git clone https://github.com/CMU-Perceptual-Computing-Lab/openpose.git
! cd openpose/ubuntu && ./install_cmake.sh && ./install_cuda.sh && ./install_cudnn.sh
! cd openpose && git pull origin master && rm -r build || true && mkdir build && cd build && cmake .. && make -j`nproc`

# example demo usage
!cd openpose && ./build/examples/openpose/openpose.bin --video examples/media/video.avi --write_json output/ --display 0 --render_pose 0

Type of Issue

• Enhancement / offering possible extensions / pull request / etc

Thanks! you've just saved me a lot of time. That'd be helpful to add in installation section.

[AlbanoBorba]

Thanks for your script, the installation works fine on google colab. However, while executing the example i got the following error:

Starting OpenPose demo...
Configuring OpenPose...
Starting thread(s)...
Auto-detecting all available GPUs... Detected 1 GPU(s), using 1 of them starting at GPU 0.
Unable to init server: Could not connect: Connection refused

(OpenPose 1.4.0:20551): Gtk-WARNING **: 16:56:00.904: cannot open display:

Any idea?

[raymanaa]

That script is a godsend ! Thank you very much, but I'm having a little problem once running it, I read a little bit and it seems to be coming from the caffe library, here's the output (I just added --logging-level 0)

https://pastebin.com/WP2hScGV

and without logging-level :

Any ideas ?

--Edit--
Nevermind, I got it to work using this #799, anyone having the same problem, I just used sed to replace the line inside the CMakeLists.txt, it's a bit hacky but it works. Here's the code just use it and build again.

!sed -i 's/execute_process(COMMAND git checkout master WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}\/3rdparty\/caffe)/execute_process(COMMAND git checkout f019d0dfe86f49d1140961f8c7dec22130c83154 WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}\/3rdparty\/caffe)/g' openpose/CMakeLists.txt

[rmc7]

I install openpose and then replace the line in the CMakeLists.txt with this code but have a same error when running the demo. #799

1.install openpose in colab with GPU
! apt update ! apt install -y cmake sudo libopencv-dev ! git clone https://github.com/CMU-Perceptual-Computing-Lab/openpose.git ! cd openpose/ubuntu && ./install_cmake.sh && ./install_cuda.sh && ./install_cudnn.sh ! cd openpose && git pull origin master && rm -r build || true && mkdir build && cd build && cmake .. && make -jnproc``

2.replace the line in cmakelist
!sed -i 's/execute_process(COMMAND git checkout master WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}\/3rdparty\/caffe)/execute_process(COMMAND git checkout f019d0dfe86f49d1140961f8c7dec22130c83154 WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}\/3rdparty\/caffe)/g' openpose/CMakeLists.txt

3.after that I want to watch a demo by this.
!cd openpose && ./build/examples/openpose/openpose.bin --video examples/media/video.avi --write_json output/ --display 0 --render_pose 0

4.but the same error appears in demo

how can I deal with..?

[raymanaa]

I install openpose and then replace the line in the CMakeLists.txt with this code but have a same error when running the demo. #799

Before building and using cmake when installing, use the sed command and then build, here's the changes I made (Didn't want to remove anything I just added one line):

1.install openpose in colab with GPU

! apt install -y cmake sudo libopencv-dev
! git clone https://github.com/CMU-Perceptual-Computing-Lab/openpose.git
! cd openpose/ubuntu && ./install_cmake.sh && ./install_cuda.sh && ./install_cudnn.sh

I am facing similar issues.Is there a way to run Open Pose on google collab?

[kylemcdonald]

i made an attempt at running open pose on colab by checking out the specific commit that was probably used at the beginning of this thread, but it didn't work for me:

! apt update
! apt install -y cmake sudo libopencv-dev
! rm -rf openpose
! git clone https://github.com/CMU-Perceptual-Computing-Lab/openpose.git
! cd openpose && git checkout 7ae6a71115763c6df7093e1bd6a72b3fdfe9ff94
! cd openpose/ubuntu && ./install_cmake.sh && ./install_cuda.sh && ./install_cudnn.sh
! sed -i 's/execute_process(COMMAND git checkout master WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}\/3rdparty\/caffe)/execute_process(COMMAND git checkout f019d0dfe86f49d1140961f8c7dec22130c83154 WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}\/3rdparty\/caffe)/g' openpose/CMakeLists.txt
! cd openpose && rm -r build || true && mkdir build && cd build && cmake .. && make -j`nproc`

and the error output is:

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:

didn´t work

[miu200521358]

Nice to meet you.
I fixed the script that introduces Openpose in Google Colab.
As of March 5, the version of cmake is 3.12, but this version seems to fail to build CUDA 10.

https://developercommunity.visualstudio.com/content/problem/354325/cmake-project-cannot-detect-cuda-10.html

1. Change the type of runtime to "GPU"
2. Update cmake
3. Introducing Openpose

Please try it if you do not mind.

[tugstugi]

If someone needs it, I have a prepared a Colab notebook to test OpenPose on YouTube videos: https://colab.research.google.com/github/tugstugi/dl-colab-notebooks/blob/master/notebooks/OpenPose.ipynb

I have also Colab notebooks for AlphaPose and DensePose: https://github.com/tugstugi/dl-colab-notebooks#pose-detection

[gineshidalgo99]

@sirramsalott I will add this to the doc! I guess I will create a new file (e.g. doc/colab.md) or something like that. Thanks for your contribution!

I will also mention all the other issues/solutions posted here in that same document. Thanks to all.

UPDATED: Added a link from doc/installation.md to this post (to be pushed in the next commit), so everyone can benefit from this. I am closing this then, as it can be accessed from the link in the doc. Thanks again!
