AttributeError: module 'cv2' has no attribute 'file python 报错

这种错误通常是因为使用了不支持的函数或属性。在这种情况下,可能是因为你在使用一个不存在的函数或属性,或者你已经导入了一个名为cv2的模块,但它并不是你要使用的那个模块。
为了解决这个问题,你可以尝试以下步骤:
1. 检查你的代码中是否存在拼写错误或语法错误。这可能会阻止正确导入模块或调用它的函数。
2. 确定你导入的模块是否与你使用的类型相等。例如,你可能导入了一个名为cv2的模块,但实际上你需要使用名为cv2.cv2或其他类似的模块。
3. 确保你安装了正确的opencv库。有时候,由于缺少某些库,opencv库可能会出现错误。
4. 重新安装opencv库。如果以上步骤无法解决您的问题,请考虑重新安装opencv库,这可能会修复库中的任何错误或损坏文件。

AttributeError: module 'cv2' has no attribute '_file_'
这个错误通常是由于OpenCV版本不兼容导致的。可以尝试更新OpenCV版本或者安装正确版本的OpenCV。以下是更新OpenCV版本的步骤:
1.卸载旧版本的OpenCV:
```shell
pip uninstall opencv-python
```
2.安装最新版本的OpenCV:
```shell
pip install opencv-python
```
如果你已经安装了正确版本的OpenCV,但仍然遇到此错误,请检查你的代码是否正确导入了OpenCV库。如果还是无法解决问题,请提供更多的上下文信息以便更好地帮助你解决问题。

I'm using python 2.7.6 and OpenCv 3.0 with the additional non-free modules. I do have xfeatures2d present in available modules and can import it, however it was as though xfeatures2d didn't contain SIFT or SURF. No matter how I called them it was the same Error: 。 引用\[3\]:在使用python版的OpenCV进行特征提取时出现"AttributeError: module ‘cv2.cv2’ has no attribute ‘xfeatures2d_SIFT’ "错误 通过网上寻找解决方法,发现是当前opencv版本(4.5)不能使用sift、surf等特征匹配算法。后面使用opencv3.4.2.16和python3.7成功运行了,运行效果如下图所示。 。
问题: AttributeError: module 'cv2' has no attribute 'FREAK_create'
回答: 这个错误通常是由于OpenCV版本的问题引起的。根据引用\[3\]中的描述,当前版本的OpenCV(4.5)不支持FREAK_create等特征匹配算法。建议尝试使用较早版本的OpenCV,如OpenCV 3.4.2.16,并确保与Python 3.7兼容,以解决这个问题。
