Installing openpose on Colab - jupyter-notebook

Question

I have been trying to install openpose on google colab using the following script.
import os
from os.path import exists, join, basename, splitext
git_repo_url = 'https://github.com/CMU-Perceptual-Computing-Lab/openpose.git'
project_name = splitext(basename(git_repo_url))[0]
if not exists(project_name):
# see: https://github.com/CMU-Perceptual-Computing-Lab/openpose/issues/949
# install new CMake becaue of CUDA10
!wget -q https://cmake.org/files/v3.13/cmake-3.13.0-Linux-x86_64.tar.gz
!tar xfz cmake-3.13.0-Linux-x86_64.tar.gz --strip-components=1 -C /usr/local
# clone openpose
!git clone -q --depth 1 $git_repo_url
!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
# install system dependencies
!apt-get -qq install -y libatlas-base-dev libprotobuf-dev libleveldb-dev libsnappy-dev libhdf5-serial-dev protobuf-compiler libgflags-dev libgoogle-glog-dev liblmdb-dev opencl-headers ocl-icd-opencl-dev libviennacl-dev
# install python dependencies
!pip install -q youtube-dl
# build openpose
!cd openpose && rm -rf build || true && mkdir build && cd build && cmake .. && make -j`nproc`
Here is a link to that colab notebook Link to colab notebook . Worked fine there. However, when I try the same script on my own colab notebook I get the following error.

Don't know why I get this error.
CMake Error: failed to create symbolic link '../../lib/libcaffe.so': operation not supported on socket
Any help would be appreciated. Thanks in advance.

There is probably some version issue of cmake, CUDA and cuDNN. Check for compatibility.
