我有一个包含所有变体的许多行的示例输入文件,而列表示组件的数量。使用sklearn与Python在数据框上执行PCA

予先导入此.txt文件为:
#!/usr/bin/env python
from sklearn.decomposition import PCA
inputfile=vcf=open('sample_input_file', 'r')
我想执行主成分分析和绘图的前两个部件(意味着前两列)
我不知道是否这种方式去读后约
sklearn
PCA的两个组成部分:
pca = PCA(n_components=2)
pca.fit(inputfile) #not sure how this read in this file
所以,我需要帮助导入我的输入文件作为一个数据帧的Python对其执行PCA
