Question

我想使用pyueye模块来操纵我的IDS相机。我已经从制造商的网站上安装了最新的驱动程序，并且可以使用uEye Cockpit应用程序管理相机。我想写一些与相机一起使用的python脚本，但是我什至无法导入pyueye模块。

我的代码：

import ctypes
from pyueye import ueye
print(ueye.__version__)

错误信息：

C:\Python\python.exe C:/Users/Karol/PycharmProjects/ids_camera/ids_test.py
Traceback (most recent call last):
File "C:\Python\lib\site-packages\pyueye\dll.py", line 165, in load_dll
dll = DLL(libinfo, libnames, os.getenv(envname))
File "C:\Python\lib\site-packages\pyueye\dll.py", line 96, in __init__
raise RuntimeError("could not find any library for {} ({})".format(libinfo, 
dllmsg))
RuntimeError: could not find any library for ueye_api (DLL_PATH: unset)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
 \File "C:/Users/Karol/PycharmProjects/ids_camera/ids_test.py", line 2, in 
<module>
     from pyueye import ueye

    from . import ueye
File "C:\Python\lib\site-packages\pyueye\ueye.py", line 54, in <module>
    get_dll_file, _bind = load_dll("ueye_api", ["ueye_api_64", "ueye_api"], 
"PYUEYE_DLL_PATH")
File "C:\Python\lib\site-packages\pyueye\dll.py", line 167, in load_dll
    raise ImportError(exc)
ImportError: could not find any library for ueye_api (DLL_PATH: unset)

Process finished with exit code 1

我已经通过pip安装了该模块，我的操作系统是Win 7 x64，我的python解释器是3.6，与ueye关联的* .dll文件也安装在C：\ Windows ...文件夹中。我也将ueye_api.dll和ueye_tools.dll文件复制到了pyueye目录，但这没有帮助。

Answer 1

我尝试将ueye_api_64.dll中的C:\Program Files\IDS\uEye\USB driver package添加到我的pyueye文件夹中。我还将此位置添加到系统变量的PATH中，这为我解决了问题。

Answer 2

尝试以下操作：

安装后重新启动计算机。
确保DLL位于C：\ Windows \ System32目录中。
将PYUEYE_DLL_PATH设置为DLL所在的目录。

如果没有任何帮助，请与IDS支持人员联系。

无法导入pyueye模块，dll错误
