利用Python计算π的值,并显示进度条 第一步:下载tqdm 第二步;编写代码 from math import * from tqdm import tqdm from time import * total,s,n,t=0.0,1,1.0,1.0 clock() while(fabs(t)>=1e-6): total+=t n+=2 s=-s t=s/n k=total*4 print("π值是{:.10f} 运行时间为{:.4f}秒".
利用TensorFlow实现多元逻辑回归,代码如下: import tensorflow as tf import numpy as np from sklearn.linear_model import LogisticRegression from sklearn import preprocessing # Read x and y x_data = np.loadtxt("ex4x.dat").astype(np.float32) y_data = np.loadtxt(&qu
