机器:64位机、win7、Python2.7。
首先,下载python,过程不赘述。
然后,下载numpy,http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
选择对应版本下载。
双击安装。
出现问题:
1、若安装过程中出现“Python version2.7 required,which was not found in the registry”,则未注册,
方法(转):新建.py文件,编辑
import sys
from _winreg import *
# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix
regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (
installpath, installpath, installpath
)
def RegisterPy():
try:
reg = OpenKey(HKEY_CURRENT_USER, regpath)
except EnvironmentError as e:
try:
reg = CreateKey(HKEY_CURRENT_USER, regpath)
SetValue(reg, installkey, REG_SZ, installpath)
SetValue(reg, pythonkey, REG_SZ, pythonpath)
CloseKey(reg)
except:
print "*** Unable to register!"
return
print "--- Python", version, "is now registered!"
return
if (QueryValue(reg, installkey) == installpath and
QueryValue(reg, pythonkey) == pythonpath):
CloseKey(reg)
print "=== Python", version, "is already registered!"
return
CloseKey(reg)
print "*** Unable to register!"
print "*** You probably have another Python installation!"
if __name__ == "__main__":
RegisterPy()
执行。
2、安装完成后,
输入from numpy import *
出现:
原因:感觉是本人64位机安装了32位python2.7,
故,重新下载numpy win32版本,
安装,
输入from numpy import *
成功。
