日前，米爾電子震撼發(fā)布MYD-JX8MPQC開發(fā)板，一經(jīng)發(fā)布就備受矚目。米爾這款開發(fā)板采用NXP第一款集成 NPU的高性能處理器i.MX 8M Plus芯片，面向AI場景，強(qiáng)大的邊緣計算能力，NXP官方給這顆處理器的定位是“能夠在工業(yè)和物聯(lián)網(wǎng)等領(lǐng)域?qū)崿F(xiàn)邊緣端高級機(jī)器學(xué)習(xí)推理”。且看試用者詳細(xì)介紹【米爾MYC-JX8MPQ評測】+ 運行 TensorFlow Lite（CPU和NPU對比），小編在此分享給大家。

【米爾MYC-JX8MPQ評測】+ 運行 TensorFlow Lite（CPU和NPU對比）—bloong

TensorFlowLite是一個開源軟件庫，專注于在移動設(shè)備和嵌入式設(shè)備上運行機(jī)器學(xué)習(xí)模型(可在http://www.tensorflow.org/lite上獲得)。它支持具有低延遲和小二進(jìn)制大小的設(shè)備上的機(jī)器學(xué)習(xí)推斷。張量流Lite還支持使用安卓操作系統(tǒng)神經(jīng)網(wǎng)絡(luò)API(NNAPI)進(jìn)行硬件加速。

我們試用一下TensorFlowLite，試用之前我們先介紹一位老前輩，當(dāng)然也是BUG的出處。

Bug一詞指在電腦系統(tǒng)或程序中，隱藏著的一些未被發(fā)現(xiàn)的缺陷或問題。但是Bug一詞是如何由來的呢?這一切起源于1947年，從一只不小飛入Mark II計算機(jī)的飛蟲說起。

擴(kuò)展閱讀：

1947年9月9日，當(dāng)人們測試Mark II計算機(jī)時，它突然發(fā)生了故障。經(jīng)過幾個小時的檢查后，工作人員發(fā)現(xiàn)了一只飛蛾被打死在面板F的第70號繼電器中。當(dāng)把這個飛蛾取出后，機(jī)器便恢復(fù)了正常。

當(dāng)時為Mark II計算機(jī)工作的著名女科學(xué)家Grace Hopper將這只飛蛾粘帖到當(dāng)天的工作手冊中，并在上面加了一行注釋，

“First actual case of bug being found”

當(dāng)時的時間是15：45.隨著這個故事的廣為流傳，越來越多的人開始使用Bug一詞來指代計算機(jī)中的設(shè)計錯誤，并把Grace Hopper上登記的那只飛蛾看作是計算機(jī)里上第一個被記錄在文檔中的Bug.

這一稱呼后來演變成表達(dá)缺陷漏洞的計算機(jī)專業(yè)術(shù)語，人們習(xí)慣地把排除程序故障叫做“debug”（除蟲）。

今天我們測試TensorFlow的image classification的主角就是老前輩grace_hopper的相片。

1、在CPU上使用移動網(wǎng)絡(luò)模型運行此示例，請使用以下命令：

root@myd-jx8mp:/usr/bin/tensorflow-lite-2.4.0/examples# ./label_image -m mobilenet_v1_1.0_224_quant.tflite -i grace_hopper.bmp -l labels.txt

運行結(jié)果如下

INFO: Loaded model mobilenet_v1_1.0_224_quant.tflite

INFO: resolved reporter

INFO: invoked

INFO: average time: 44.477 ms

INFO: 0.780392: 653 military uniform

INFO: 0.105882: 907 Windsor tie

INFO: 0.0156863: 458 bow tie

INFO: 0.0117647: 466 bulletproof vest

INFO: 0.00784314: 835 suit

2、要使用xnnpack委托在CPU上運行示例應(yīng)用程序，請使用-x1開關(guān)

./label_image -m mobilenet_v1_1.0_224_quant.tflite -i grace_hopper.bmp -l labels.txt -x 1

運行結(jié)果如下

INFO: Loaded model mobilenet_v1_1.0_224_quant.tflite

INFO: resolved reporter

INFO: Created TensorFlow Lite XNNPACK delegate for CPU.

INFO: Applied XNNPACK delegate.

INFO: invoked

INFO: average time: 44.514 ms

INFO: 0.780392: 653 military uniform

INFO: 0.105882: 907 Windsor tie

INFO: 0.0156863: 458 bow tie

INFO: 0.0117647: 466 bulletproof vest

INFO: 0.00784314: 835 suit

3、若要在GPU/NPU硬件加速器上使用相同的模型運行該示例，請?zhí)砑?a1命令行參數(shù)。要區(qū)分3DGPU和NPU，請使用USE_GPU_INFERENCE開關(guān)。例如，對于NPU硬件加速器，請使用以下命令：

USE_GPU_INFERENCE=0 ./label_image -m mobilenet_v1_1.0_224_quant.tflite -i grace_hopper.bmp -l labels.txt -a 1

運行結(jié)果如下

INFO: Loaded model mobilenet_v1_1.0_224_quant.tflite

INFO: resolved reporter

INFO: Created TensorFlow Lite delegate for NNAPI.

INFO: Applied NNAPI delegate.

INFO: invoked

INFO: average time: 2.773 ms

INFO: 0.768627: 653 military uniform

INFO: 0.105882: 907 Windsor tie

INFO: 0.0196078: 458 bow tie

INFO: 0.0117647: 466 bulletproof vest

INFO: 0.00784314: 835 suit

3、使用Python3運行

root@myd-jx8mp:/usr/bin/tensorflow-lite-2.4.0/examples# python3 label_image.py

運行結(jié)果

INFO: Created TensorFlow Lite delegate for NNAPI.

Applied NNAPI delegate.

Warm-up time: 6612.9 ms

Inference time: 3.0 ms

0.870588: military uniform

0.031373: Windsor tie

0.011765: mortarboard

0.007843: bow tie

0.007843: bulletproof vest

從運行結(jié)果來看同樣的圖片，NPU運行要比CPU快很多， NPU和CPU運算結(jié)果相差不大，NNAPI運行結(jié)果相似度更高。

【米爾MYC-JX8MPQ評測】運行TDengine—bloong

因為之前的項目上有用到濤思數(shù)據(jù)庫，后面項目上可能也會用到數(shù)據(jù)庫，所以在這個板子上運行試試看

TDengine 社區(qū)版是一開源版本，采用的是AGPL許可證，是一個處理中小規(guī)模的物聯(lián)網(wǎng)數(shù)據(jù)平臺。它具備高效處理物聯(lián)網(wǎng)數(shù)據(jù)所需要的所有功能，包括:

類SQL查詢語言來插入或查詢數(shù)據(jù)

支持C/C++, Java(JDBC), Python, Go, RESTful, and Node.JS 等開發(fā)接口

通過TDengine Shell或Python/R/Matlab可做各種Ad Hoc查詢分析

通過連續(xù)查詢，支持基于滑動窗口的流式計算

引入超級表，讓設(shè)備之間的數(shù)據(jù)聚合通過標(biāo)簽變得簡單、靈活

內(nèi)嵌消息隊列，應(yīng)用可訂閱最新的數(shù)據(jù)

內(nèi)嵌緩存機(jī)制，每臺設(shè)備的最新狀態(tài)或記錄都可快速獲得

無歷史數(shù)據(jù)與實時數(shù)據(jù)之分，對應(yīng)用而言，透明且完全一樣

分布式架構(gòu)，支持線性擴(kuò)展，以保證任何規(guī)模的數(shù)據(jù)量都可以處理

支持多副本，無單點故障，以保證系統(tǒng)的高可用與高可靠
