Heyyy,所以我正在跟踪,它要求我安装sklearn、quandl和。
不幸的是,视频作者正在使用Windows,没有解释如果在Mac上该做什么。我想也许我可以使用自制软件,所以我安装了自制软件,并尝试了brew安装sklearn,但这是行不通的。
Error: No available formula with the name "sklearn"
当我尝试pip安装sklearn时,我得到了
-bash: pip: command not found
我读过的用户酸性垃圾:“一家酿造的python已经有了pip。”我第一次读的时候就不明白了。现在,我知道一些Python安
Mac似乎已经安装了Python。brew doctor产生以下结果:
brew doctor

我正在尝试安装Ansible,但由于某些原因,我永远无法获得干净的安装。使用apt-get install ansible,然后执行ansible --version,我会得到以下输出:

我在python中创建了一个函数(已经导入了'time'):
def a():
t = time.time()
s = [False for x in xrange(1000000)]
print time.time()-t
在这台机器上(64位Windows 7,Python2.7.x),我反复按下箭头,只是为了好玩,测试了这个函数的运行。或者是看跑步时间。它似乎在0.08s和0.18s之间振荡。
但后来发生了一些奇怪的事情:
>>> a()
0.140000104904
>>> a()
0.138000011444
我是Python的新来者。我尝试这样从c++调用python脚本(在Raspberry Pi中)。
std::string pythonCommand = "python Callee.py \""+a+"\" "+b;
int res = system(pythonCommand.c_str());
在运行之后,我得到了这个。
python: can't open file 'Callee.py': [Errno 2] No such file or directory
但是我可以用命令行成功地运行Callee.py,并
