注：在以上文章中会出现以下几个问题，目前均已经解决，上述我写的代码没有问题

bug修复

1、报错AttributeError: module 'radiomics.featureextractor' has no attribute 'RadiomicsFeaturesExtractor'

将RadiomicsFeaturesExtractor库修改为RadiomicsFeatureExtractor

2、ruamel.yaml.constructor.DuplicateKeyError: while constructing a mapping in "D:/Params.yaml", line 34, column 3 found duplicate key "shape" with value "None" (original value: "None") in "D:/Params.yaml", line 37, column 3 To suppress this check see: Departure from previous API — Python YAML package documentation-keys Duplicate keys will become an error in future releases, and are errors by default when using the new API.

将yaml配置文件中的第37行注释掉即可

3、AttributeError: 'RadiomicsFeatureExtractor' object has no attribute '_enabledImagetypes'

将：

print("Enabled filters:\n\t", extractor._enabledImagetypes)
print("Enabled features:\n\t", extractor._enabledFeatures)

修改为：

print("Enabled filters:\n\t", extractor.enabledImagetypes)
print("Enabled features:\n\t", extractor.enabledFeatures)

运行结果：
