My system: Win10  
python:3.5;  
OTB Version:7.2.0

I have set PYTHONPATH to path/lib/python and the OTB\_APPLICATION\_PATH to path/lib/otb/applications.  
when I import otbApplication,I got the error message:

Python 3.5.4 |Continuum Analytics, Inc.| (default, Aug 14 2017, 13:41:13) [MSC v.1900 64 bit (AMD64)] on win32  
Type “help”, “copyright”, “credits” or “license” for more information.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):  
File “”, line 1, in   
File “D:\software\python\OTB-7.2.0-Win64\OTB-7.2.0-Win64\lib\python\otbApplication.py”, line 17, in   
\_otbApplication = swig\_import\_helper()  
File “D:\software\python\OTB-7.2.0-Win64\OTB-7.2.0-Win64\lib\python\otbApplication.py”, line 16, in swig\_import\_helper  
return importlib.import\_module('_otbApplication’)  
File "D:\software\python\python3\Anaconda3\envs\otb\lib\importlib\_init_.py", line 126, in import\_module

ImportError: DLL load failed: 找不到指定的模块。

I would be grateful if anyone knew how to configure the OTB Python environment.
