图像类型 PNG 不允许使用 GCP DLP 进行去标识化

Image Type PNG not allowed for de-identification with GCP DLP

我收到这个错误: google.api_core.exceptions.InvalidArgument: 400 BytesType.IMAGE_PNG 不支持与去标识化一起使用。

我有这段代码,它应该可以处理图像,但后来我收到此错误,指出它不受支持。我做错了什么或相信错误吗?有没有可能是我在试用期导致的这个错误?

# Call the API
response = dlp.deidentify_content(

图像仅在 RedactImage 方法中受支持。
