thanks for any suggestions!

I have the same problem ;-)

I have the same problem too ;-)

[apache2046]

I have the same problem too ;-)

i fix it with sudo apt install protobuf-compiler

May be you can modify the third_party CMakelists, I have solved it~

I got the same problem on Ubuntu 18.04 LTS, and found this is because my protobuf from apt is too old (v3.0.0). Compiling it from source turns out solving the problem:

sudo apt-get install autoconf automake libtool curl make g++ unzip -y
git clone https://github.com/google/protobuf.git
cd protobuf
git submodule update --init --recursive
./autogen.sh
./configure
make -j8
make check
sudo make install
sudo ldconfig

@grapeot thanks that compiled protoc for me. Additionally I had to change the PATH variable to protoc location (I had /usr/local/bin) because anaconda's protoc came first

[chegnyanjun]

@anuar12,I have the same situation as you and i am a newcomer in DL, Can you tell how to do it?Hope for your reply,tkx.

This fixed the issue for me. +1
