./jetsoninfo.py
results in

Traceback (most recent call last): File "/home/zeno/software/jetsonUtilities/jetsonInfo.py", line 22, in <module> (key, _, value) = line.partition("=") TypeError: a bytes-like object is required, not 'str'

When I run python jetsonInfo.py I see

Then I did
sudo apt install nvidia-jetpack
sudo apt show nvidia-jetpack shows

but python jetsonInfo.py shows me same result

jetsonUtilities$ python jetsonInfo.py

 NVIDIA Jetson TX2
 L4T 32.4.2 [ JetPack UNKNOWN ]
 Ubuntu 18.04.4 LTS
 Kernel Version: 4.9.140-tegra
 CUDA 10.2.89

Possibly a known issue, since this information no longer appears in /proc/cpuinfo or lscpu.

When run py jetsonInfo.py on TX2, getting
Unable to find file /etc/nv_tegra_release

What I'm missing

Thanks

Hi, this happens on a fresh install of "Developer Preview of JetPack 4.4", downloaded from https://developer.nvidia.com/jetson-nano-sd-card-image, which redirects you to download a file called nv-jetson-nano-sd-card-image-r32.4.2.zip of size 5.91 GB, exactly 6,347,594,220 bytes.

When running jetsonInfo.py it says something about a TX1 although I'm running it on a Nano.
Following is ouput:

drakorg@drakorg-jetpack44:~/workspace/nspi/scripts/jetson-nano/jetsonUtilities$ sudo ./jetsonInfo.py
 NVIDIA Jetson TX1
 L4T 32.4.2 [ JetPack UNKNOWN ]
 Ubuntu 18.04.4 LTS
 Kernel Version: 4.9.140-tegra
 CUDA 10.2.89

It also states that the Jetpack version is unknown, when I would expect it to detect it as 4.4.
Thank you.
Best regards,
Eduardo

Describe the issue
OpenCV 4.1.1 cmake doesn't find cuDNN when using JetPack 4.4

System

• Jetson Nano
• cmake 3.16.3
• L4T 32.4.3 [ JetPack 4.4 ]
  • Ubuntu 18.04.5 LTS
  • Kernel Version: 4.9.140-tegra
• CUDA 10.2.89
  • CUDA Architecture: 5.3
• OpenCV version: 4.1.1
  • OpenCV Cuda: NO
• CUDNN: 8.0.0.180
• TensorRT: 7.1.3.0
• Vision Works: 1.6.0.501
• VPI: 0.3.7

To Reproduce

1. Download and install the Jetson Nano SD Card image
   https://developer.nvidia.com/jetson-nano-sd-card-image
   JP 4.4 from 2020/07/07
2. optional: install cmake 3.16.3
3. Checkout this repo and run:
   ./buildOpenCV.sh |& tee openCV_build.log
   In the cmake config you can see that cuDNN -> NO is diplayed and OpenCV is built without it

Expected behavior
cuDNN -> YES is detected by cmake and OpenCV is built with cuDNN

Additional context
I was using a newer version of cmake as my build pipline requires this. So there's no issue related reason for the updated cmake version. This is likely not the cause for the error.
