问题
When I run this:
protoc --python_out=. .\object_detection\protos\anchor_generator.proto
on a tensorflow object detection file on the command line, I get:
'protoc' is not recognized as an internal or external command, operable program or batch file.
I followed all instructions in protoc object_detection/protos/*.proto: No such file or directory, but they never worked for me
In addition to the searches I made, I tried this command:
py-3.6 -m pip install protobuf
and it works for me.
I typed the command again
python_out=. .\object_detection\protos\anchor_generator.proto
But it still fails and this:
C:\Users\laptop market\Downloads\bin\protoc object_detection/protos/*.proto --py_out=.
also fails.

Hey I got the solution you have to save the protoc.exe file which is located in the bin file to C:\Users\Satyarth\AppData\Local\Programs\Python\Python36\Scripts and it will solve the problem and if it still not give the above path to the enviroment variables and it will surely help that. Change the "Satyarth" from the path and use yours

Better you just go to this directory: https://www.github.com/google/protobuf/releases
then just download the protoc.py file which suits your OS virsion and extract that one. you will get a protoc.exe file, then place it on your local machine

Depending on your platform, you might have to install protobuf locally. See the docs for more detailed instructions.

First of all consider installing Protobuf Compiler inside the C:\Program Files folder. Then you need to compile protobuf every time you want to use Tensorflow Object Detection API. To do this, open cmd in the ../models/research directory and run
“C:\Program Files\protoc-<PROTO_VERSION>\bin\protoc.exe” object_detection/protos/*.proto --python_out=.
where <PROTO_VERSION> is the version of protobuf compiler, you're using (for example protoc-3.5.1-win64 or the name of the folder you've picked for the protobuf).
Be advised, that you should compile protobuf in the every cmd window that is launched to work with Object Detection.
