DeepStream SDK on NVIDIA Jetson

What is DeepStream SDK?

Build and deploy AI-powered Intelligent Video Analytics apps and services. DeepStream offers a multi-platform scalable framework with TLS security to deploy on the edge and connect to any cloud.

• Develop in C/C++ or Python
• Built for scalability - one application for NVIDIA T4 and Jetson platforms
• Highest throughput for object detection, image classification and semantic segmentation models
• Deploy models in native DL frameworks such as Pytorch and TensorFlow for inference
• IoT integration interface with Kafka, MQTT and AMQP
• Turnkey integration with AWS IoT and Microsoft Azure IoT
• Multi-GPU, multi-stream and batching support for high throughput inference

Why do we use DeepStream SDK?

DeepStream SDK design for NVIDIA Jetson Family. So, For the best performance.

Sample Python Applications

We currently provide the following sample applications:

• deepstream-test1 -- 4-class object detection pipeline
• deepstream-test2 -- 4-class object detection, tracking and attribute classification pipeline
• deepstream-test3 -- multi-stream pipeline performing 4-class object detection
• deepstream-test4 -- msgbroker for sending analytics results to the cloud
• deepstream-imagedata-multistream -- multi-stream pipeline with access to image buffers
• deepstream-ssd-parser -- SSD model inference via Triton server with output parsing in Python
• deepstream-test1-usbcam -- deepstream-test1 pipeline with USB camera input
• deepstream-test1-rtsp-out -- deepstream-test1 pipeline with RTSP output

Detailed application information is provided in each application's subdirectory under apps.

deepstream-test1 python 

In this sample, we first create one instance of "nvinfer", referred as the pgie.
This is our 4 class detector and it detects for "Vehicle , RoadSign, TwoWheeler,
Person".

Run Linux Command

jetson@nano:~/deepstream_python_apps/apps/deepstream-test1$ python deepstream_test_1.py /home/jetson/Videos/streams/sample_720p.h264

OLED Display on NVIDIA Jetson Nano

 

OLED Display on NVIDIA Jetson Nano

On JetBot (JetBot is an open-source robot based on NVIDIA Jetson Nano.) It has 128x64 OLED and Connector. it's good idea for show something. 

We can use 128x64 OLED Display. ( more popular in the market and low cost )

NVIDIA Jetson Nano Bitcoin Mining

What is Bitcoin Mining?

With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. This provides a smart way to issue the currency and also creates an incentive for more people to mine.

Why is Monero Coin ( XMR ) ?

Unlike many cryptocurrencies that are derivatives of Bitcoin, Monero is based on the CryptoNote protocol and possesses significant algorithmic differences relating to blockchain obfuscation.
By providing a high level of privacy, Monero is fungible, meaning that every unit of the currency can be substituted by another unit. These units are indistinguishable from one another. This makes Monero different from public-ledger cryptocurrencies like Bitcoin, where addresses previously associated with undesired activity can be blacklisted and refused by network members.

Can the NVIDIA Jetson Nano be used for Bitcoin mining?

It can, just not efficiently.

Then for education purpose.

How many it can?   only 16.xx H/s

if you have 1600 H/s you will get 0.00002 BTC/week.

But NVIDIA Jetson Nano can get only 16 H/s.

Power Consumption of NVIDIA Jetson Nano

use jtop command line

Mining Software

xmrMiner - A CUDA based miner for Monero ( https://github.com/xmrMiner/xmrMiner )

xmrMiner 0.3.0 is ready for the Monero hardfork v7
