【前言】 【米爾-瑞芯微RK3576核心板及開發板】具有6TpsNPU以及GPU，因此是學習機器學習的好環境，為此結合《深度學習的數學——使用Python語言》 1、使用vscode 連接遠程開發板 2、使用conda新建虛擬環境： - root@myd-lr3576x-debian:/home/myir/pro_learn# conda create --name myenv python=3.9
執行結果如下：
root@myd-lr3576x-debian:/home/myir/pro_learn# conda create --name myenv python=3.9

- root@myd-lr3576x-debian:/home/myir/pro_learn#
然后再激活環境： - root@myd-lr3576x-debian:/home/myir/pro_learn# conda activate myenv
- (myenv) root@myd-lr3576x-debian:/home/myir/pro_learn#
2、查看python版本號： - (myenv) root@myd-lr3576x-debian:/home/myir/pro_learn# python --version
- Python 3.9.20
3、使用conda install numpy等來安裝組件，安裝好后用pip list查看
編寫測試代碼：
- import numpy as np
- from sklearn.datasets import load_digits
- from sklearn.neural_network import MLPClassifier
- d = load_digits()
- digits = d["data"]
- labels = d["target"]
- N = 200
- idx = np.argsort(np.random.random(len(labels)))
- xtest, ytest = digits[idx[:N]], labels[idx[:N]]
- xtrain, ytrain = digits[idx[N:]], labels[idx[N:]]
- clf = MLPClassifier(hidden_layer_sizes=(128, ))
- clf.fit(xtrain, ytrain)
- score = clf.score(xtest, ytest)
- pred = clf.predict(xtest)
- err = np.where(pred != ytest)[0]
- print("score:", score)
- print("err:", err)
- print("actual:", ytest[err])
- print("predicted:", pred[err])
在代碼中，使用MLPClassifier對象進行建模，訓練測試，訓練數據集非�？�，訓練4次后可以達到0.99:
【總結】
米爾的這款開發板，搭載3576這顆強大的芯片，搭建了深度學習的環境，進行了基礎的數據集訓練，效果非常好！在書中記錄訓練要幾分鐘，但是這在這款開發板上測試，只要幾秒鐘就訓練完畢，書中說總體準確率為0.97，但是我在這款開發板上有0.99的良好效果！
