Hi
I’m thinking of using Detectron 2 with Jetson NX.
However, I get an error during the installation.
(environment)
Jetpack 4.4
CUDA 10.2
cuDNN 8.0
Python 3.6.9
Pytorch 1.5
torchvision 0.2.2.post3
(Execution command)
python3 -m pip install ‘git+https://github.com/facebookresearch/detectron2.git’
Do you know the cause?
Hi,
We can build detectron2 with the following command.
Could you give it a try?
$ sudo apt-get install libjpeg-dev zlib1g-dev
$ git clone https://github.com/facebookresearch/detectron2.git
$ python3 -m pip install -e detectron2
Thanks.
Hi
Thank you for your reply.
I ran them in order.
However, an error occurred while executing the last line.
By the way, I’m using pip-20.3.3.
python3 -m pip install -e detectron2

what is the reason.
Hi,
Just confirm we can install it without issue.
Could you follow our steps and try it again?
1. Reflash your device with JetPack4.4.1
2. Install PyTorch v1.7.0 from the instruction below:
3. Install Detectron2
Please see the instruction shared on Jan 8.
$ python3 -m pip install -e detectron2

Hi
Unused I re-set up and installed using the new Jetson NX and MicroSD (32GB).
(Unused item purchased as a spare)
However, I get an error when installing Detectron2.
Here are the steps I took:
①, Jetson NX initial settings
I flashed Jetpack 4.4.1 to MicroSD.
The procedure was performed with reference to the following.(Windows steps)
https://developer.nvidia.com/embedded/learn/get-started-jetson-xavier-nx-devkit#prepare
As a result, Jetson NX has started.
②、apt upgrade
I updated the package by following the steps below.
＄ sudo apt update
＄ sudo apt upgrade
③, install Pytorch 1.7
I installed Pytorch by referring to the following Pytorch description.
Jetson Zoo - eLinux.org
The specific command is:
＄ sudo apt-get install python3-pip
＄ pip3 install Cython
＄ pip3 install numpy torch-1.7.0-cp36-cp36m-linux_aarch64.whl
④, installation of Detectron 2
With reference to the previous answer, I ran the command as follows:
But the last command gives an error.
＄ sudo apt-get install libjpeg-dev zlib1g-dev
＄ git clone GitHub - facebookresearch/detectron2: Detectron2 is a platform for object detection, segmentation and other visual recognition tasks.
＄ python3 -m pip install -e detectron2

what is the reason?
Are there any fatal mistakes?
Hi,
The error indicates a missing library.
Please install it with the following command and try it again.
$ sudo apt-get install libopenmpi2
Thanks.
