在python的sklearn中没有内置的函数来实现这一点。 在我的research中,我发现“精确度分数”err(组件)可以通过 ? 组件的最佳数量将具有最小的误差(C)。 根据下面的测试代码,如何在python中实现精度分数? import numpy as np
import pandas as pd
from sklearn.decomposition import NMF
X = np.random.rand(40, 100) # create matrix for NMF
c = 4
model = NMF(n_components=c, init='random
我正在尝试在ansible playbook中执行命令docker-compose -f dev.yml build。但是得到了错误command 'gcc' failed with exit status 4。我已经在尝试安装python-dev和python3-dev库了。在攻略之外(来自shell)构建是成功的。

昨晚,我遇到了一个叫Jython的术语,这对我来说有点陌生,所以我开始阅读它,只是为了增加我对Python的困惑。我也从未真正使用过Python。这就是我所困惑的。
Python is implemented in C --这是否意味着解释器是用C编写的,还是解释器将其源代码转换为C呢?
CPython不过是最初的Python &这个词是后来发明出来的,是为了区别它和Jython -是真的还是假的?
既然Python是用C实现的(不太确定这意味着什么),但这是否意味着python可以与任何C代码无缝集成。
Jython是一种新的编程语言,还是它的语法和其他编程结构看起来

当我开始学习如何测试一个程序时,我学到的就是用与测试程序相同的语言使用一个库或包。例如,
- if a tested program is written in Python, its testing program is also written in Python and uses `UnitTest` class in the python standard library
- if a tested program is written in C++, its testing program is also written in C++ and uses some test
