How do I disable Tensorflow logging Output

[seungtaek94]

Hi.

Is there any way to disable tensorflow logging information that like below?

In python i can disable Tensorflow logging information like blow

import os
os.environ["TF_CPP_MIN_LOG_LEVEL"] = "3"

I tried using putenv("TF_CPP_MIN_LOG_LEVEL=3"); when i using c++ with cppflow2 but it doesn't work :(

Hi,

For me using putenv("TF_CPP_MIN_LOG_LEVEL=3") works perfectly. Perhaps you added it to your code late, and TF already started? Also you can try to run your executable like this:

TF_CPP_MIN_LOG_LEVEL=3 ./executable

I put putenv("TF_CPP_MIN_LOG_LEVEL=3") code in top of my main function.

But i think TF already run. Even if i set the breakpoint before putenv, TF logs are come up..

sorry for many questions. actually I m not friendly with c++..

Can u tell me when TF start..?

Are you running your code with optimization flags like -O3. If so, can you try without?

I tried run the code with optimization flags /Od(disable) in VS but it shows same result .

I solved this problem.

Set /DELAYLOAD:"tensorflow.dll(linker -> input -> DelayLoadDLLs in visual studio project setting).

Then write code that putenv("TF_CPP_MIN_LOG_LEVEL=3"); top of my main function.

I'm glad you finally made it work!
