注：在以上文章中會出現(xiàn)以下幾個問題，目前均已經(jīng)解決，上述我寫的代碼沒有問題

bug修復(fù)

1、報(bào)錯AttributeError: module 'radiomics.featureextractor' has no attribute 'RadiomicsFeaturesExtractor'

將RadiomicsFeaturesExtractor庫修改為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.

將yaml配置文件中的第37行注釋掉即可

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

將：

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

修改為：

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