我有一个使用协议缓冲区的python应用程序。我试图让它在Docker中运行，但是当我执行docker run时它会抛出错误：
以下是Dockerfile内容：
FROM python:3.5-onbuild
CMD [ "python", "./main.py" ]
这是错误：
bash-3.2$ docker run gcr.io/skroot-com/geo-boundary-refiner:0.1
Traceback (most recent call last):

TypeError: Couldn't build proto file into descriptor pool!
Invalid proto descriptor for file "image_info.proto":

image_info.proto: Import "skroot/schema/pipeline/matrix.proto" has not been loaded.
skroot.schema.pipeline.ImageInfo.Image.location: "skroot.schema.pipeline.CloudStorageLocation" seems to be defined in "cloud_storage_location.proto", which is not imported by "image_info.proto". To use it here, please add the necessary import.
skroot.schema.pipeline.ImageInfo.TranscodedImage.matrix: "skroot.schema.pipeline.Matrix" seems to be defined in "matrix.proto", which is not imported by "image_info.proto". To use it here, please add the necessary import.
在image_info.proto文件中，导入了抱怨的.proto文件：
import "skroot/schema/pipeline/cloud_storage_location.proto";
import "skroot/schema/pipeline/matrix.proto";
生成的protobuf文件位于skroot/schema/pipeline/目录中。
我很困惑，因为它在本地运行。只有当我尝试在Docker中运行它时才会出现这些错误。
