I am using AWS EC2 Ubuntu 18.04. I was able to install everything successfully. While I was trying to load Detectron2LayoutModel, I get following error

python3: Relink `/lib/x86_64-linux-gnu/libsystemd.so.0' with `/lib/x86_64-linux-gnu/librt.so.1' for IFUNC symbol `clock_gettime'
python3: Relink `/lib/x86_64-linux-gnu/libudev.so.1' with `/lib/x86_64-linux-gnu/librt.so.1' for IFUNC symbol `clock_gettime'
Segmentation fault (core dumped)

To Reproduce
Steps to reproduce the behavior:
I launched a t2.large AWS Ubuntu 18.04 and ran following command

1. sudo apt-get update
2. sudo apt install python3-pip -y
3. python3 -m pip install --upgrade pip
4. pip3 install scikit-build
5. pip3 install layoutparser torchvision && pip3 install "detectron2@git+https://github.com/facebookresearch/[email protected]#egg=detectron2"

and then ran the following script.

import layoutparser as lp
model = lp.Detectron2LayoutModel('lp://PubLayNet/mask_rcnn_X_101_32x8d_FPN_3x/config',extra_config=["MODEL.ROI_HEADS.SCORE_THRESH_TEST", 0.65],
                                 label_map={0: "Text", 1: "Title", 2: "List", 3:"Table", 4:"Figure"})

Output -

python3: Relink `/lib/x86_64-linux-gnu/libsystemd.so.0' with `/lib/x86_64-linux-gnu/librt.so.1' for IFUNC symbol `clock_gettime'
python3: Relink `/lib/x86_64-linux-gnu/libudev.so.1' with `/lib/x86_64-linux-gnu/librt.so.1' for IFUNC symbol `clock_gettime'
Segmentation fault (core dumped)

Environment

1. Ubuntu 18.04 - AWS t2.large Instance
2. layout parser version = 0.3.2
3. Python 3.6.9

Any one else facing this issue?
