- #
- # To activate this environment, use
- #
- # $ conda activate myenv
- #
- # To deactivate an active environment, use
- #
- # $ conda deactivate
- root@myd-lr3576x-debian:/home/myir/pro_learn#
然后再激活环境：
- root@myd-lr3576x-debian:/home/myir/pro_learn# conda activate myenv
- (myenv) root@myd-lr3576x-debian:/home/myir/pro_learn#
2、查看python版本号：
- (myenv) root@myd-lr3576x-debian:/home/myir/pro_learn# python --version
- Python 3.9.20
3、使用conda install numpy等来安装组件，安装好后用pip list查看
编写测试代码：
- 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])
在代码中，使用MLPClassifier对象进行建模，训练测试，训练数据集非常快，训练4次后可以达到0.99:
【总结】
米尔的这款开发板，搭载3576这颗强大的芯片，搭建了深度学习的环境，进行了基础的数据集训练，效果非常好！在书中记录训练要几分钟，但是这在这款开发板上测试，只要几秒钟就训练完毕，书中说总体准确率为0.97，但是我在这款开发板上有0.99的良好效果！
