尝试编译协议文件时出错：文件未找到或有错误

Question

我正在尝试使用以下命令编译 protoc 文件：

protoc/bin/protoc models/research/object_detection/protos/*.proto --python_out=.

但我在 cmd 上得到这个输出

object_detection/protos/flexible_grid_anchor_generator.proto: File not found.
object_detection/protos/grid_anchor_generator.proto: File not found.
object_detection/protos/multiscale_anchor_generator.proto: File not found.
object_detection/protos/ssd_anchor_generator.proto: File not found.
models/research/object_detection/protos/anchor_generator.proto:5:1: Import "object_detection/protos/flexible_grid_anchor_generator.proto" was not found or had errors.

那么可能是什么问题谢谢

您需要在正确的目录中运行 protobuf 编译器。在这种情况下，它将是models/research：

$ cd models/research
$ ../../protoc/bin/protoc object_detection/protos/*.proto --python_out=.

protobuf 文件将被编译为 python。在目录中object_detection/protos/，您应该有以 protobuf 文件命名的 python 文件（即<name_protobuf>_pb2.py）。

这些 protobuf 文件中有相对导入，因此 protobuf 编译器在正确的目录中运行非常重要。您有一个提示，这可能是错误，因为File not Found错误消息列出了与当前目录不同的路径。
