写一个可以人物图像为边缘填充绘制词云图的python代码

以下是一个可以将人物头像作为边缘填充绘制词云图的Python代码示例：

首先，需要安装必要的库：

!pip install wordcloud
!pip install matplotlib
!pip install numpy
!pip install Pillow
!pip install requests
!pip install imageio

然后，可以先定义一个函数，用于获取人物头像的图片：

import requests
from PIL import Image
import numpy as np
import os
import io
import imageio

def get_image(url):
    response = requests.get(url)
    img = Image.open(io.BytesIO(response.content)).convert("RGBA")
    img_arr = np.array(img)
    return img_arr

接下来，定义一个函数，用于绘制词云图：

from wordcloud import WordCloud, STOPWORDS
import matplotlib.pyplot as plt

def generate_wordcloud(text, mask_image):
    stopwords = set(STOPWORDS)
    wc = WordCloud(background_color="white", max_words=2000, mask=mask_image,
                   stopwords=stopwords, contour_width=3, contour_color='firebrick')
    wc.generate(text)
    plt.figure(figsize=(10, 10))
    plt.imshow(wc, interpolation='bilinear')
    plt.axis("off")
    plt.show()

最后，可以调用函数，生成词云图：

url = 'https://avatars.githubusercontent.com/u/16923247?v=4'
img_arr = get_image(url)

text = "Python is a widely used high-level programming language for general-purpose programming, created by Guido van Rossum and first released in 1991. An interpreted language, Python has a design philosophy which emphasizes code readability (notably using whitespace indentation to delimit code blocks rather than curly brackets or keywords), and a syntax which allows programmers to express concepts in fewer lines of code than possible in languages such as C++ or Java. The language provides constructs intended to enable writing clear programs on both a small and large scale."

generate_wordcloud(text, img_arr)

这样就可以生成一个以人物头像为边缘填充的词云图了。
