import matplotlib.pyplot as plt plt.hist(x = '需要处理的数据',bins = '需要分割的精度') plt.xlabel('x轴标签') plt.ylabel('y轴标签') plt.title('总标题') plt.show() bins? 按照我的个人实验结果,应该是关于精度的变量,跟组数无关 不妨bins = 10 or 100 o
通过查阅matplotlib文档[3],我们知道了bins参数的解释如下: bins:int or sequence or str, default:rcParams["hist.bins"](default:10) If bins is an integer, it defines the number of equal-width bins in the range. If bins is a sequence, it defines the bin edges, including the left edge of ...
通过一个简单的实例来演示如何在PyTorch中使用bins参数。 importtorchimportmatplotlib.pyplotasplt# 生成一组随机数据data=torch.randn(1000)# 生成直方图hist=torch.histc(data,bins=20,min=-3,max=3)# 绘制直方图plt.figure(figsize=(10,6))plt.bar(torch.arange(20),hist.numpy(),width=0.8,color='lightblue...

hist,bins = np.histogram(img.ravel(),256,[0,256]) 1. 2. 绘制直方图: 有两种方法来绘制直方图: Short Way(简单方法):使用 Matplotlib 中的绘图函数。 Long Way(复杂方法):使用 OpenCV 绘图函数 import cv2 from matplotlib import pyplot as plt ...
