iPython: DLL load failed: The specified module could not be found; plain Python fine -


i keep getting (well known) error in ipython. yet, same import works fine in plain python. (python 3.3.5, see details below)

ipython:

python 3.3.5 (v3.3.5:62cf4e77f785, mar  9 2014, 10:37:12) [msc v.1600 32 bit (intel)] type "copyright", "credits" or "license" more information.  ipython 2.0.0 -- enhanced interactive python. ?         -> introduction , overview of ipython's features. %quickref -> quick reference.      -> python's own system. object?   -> details 'object', use 'object??' details.  in [1]: import test1 --------------------------------------------------------------------------- importerror                               traceback (most recent call last) <ipython-input-7-ddb30f03c287> in <module>() ----> 1 import test1 importerror: dll load failed: specified module not found.

python (not loads fine, works):

$ python python 3.3.5 (v3.3.5:62cf4e77f785, mar  9 2014, 10:37:12) [msc v.1600 32 bit (intel)] on win32 type "help", "copyright", "credits" or "license" more information. >>> import test1 >>>

now, dependency walker on test1.pyd shows this

[ ? ]  libgcc_s_dw2-1.dll  error opening file. system cannot find file specified (2). [ ? ]  libstdc++-6.dll     error opening file. system cannot find file specified (2). [ ? ]  python33.dll        error opening file. system cannot find file spec

i overwrote sys.path in ipython 1 plain python. file test1.pyd in c:\test.

['c:\\test',  'c:\\winpython-32bit-3.3.5.0\\python-3.3.5\\python33.zip',  'c:\\winpython-32bit-3.3.5.0\\python-3.3.5\\dlls',  'c:\\winpython-32bit-3.3.5.0\\python-3.3.5\\lib',  'c:\\winpython-32bit-3.3.5.0\\python-3.3.5',  'c:\\winpython-32bit-3.3.5.0\\python-3.3.5\\lib\\site-packages',  'c:\\winpython-32bit-3.3.5.0\\python-3.3.5\\lib\\site-packages\\fonttools',  'c:\\winpython-32bit-3.3.5.0\\python-3.3.5\\lib\\site-packages\\win32',  'c:\\winpython-32bit-3.3.5.0\\python-3.3.5\\lib\\site-packages\\win32\\lib',  'c:\\winpython-32bit-3.3.5.0\\python-3.3.5\\lib\\site-packages\\pythonwin']

why import work in plain python not in ipython?

i have same problem occurred. after hours looking , thinking. difference environment variables between interpret ide choose use. ( plain python , ipython or pycharm etc.) think can use %env in ipython check text. use (works in python 3.7)

import os os.environ

check text. if there differences. many should set right 1 before run. there many way set envs. example 

1、os.environ['环境变量名称']='环境变量值' #其中key和value均为string类型  2、os.putenv('环境变量名称', '环境变量值')

hope helps you.~~~///(^v^)\\~~~
