I started a new machine learning project.
In according to this document (https://www.tensorflow.org/tensorboard/tensorboard_profiling_keras)
TF with Tensorboard appears to support GPU profiling. So, i used the same code in my Jupyter Notebook for testing.
The sample code generates profiling resulting. However, there is no GPU tracing information in resulting file. (only CPU)
This is my main problem.
I am using two RTX 2080 TI graphic cards.
And also, they were working when running the code.
The sample code does not use MirroredStrategy. So, i could see the one of them was running.
At first, i thought Tensorboard was the problem. But,i realized soon that TF does not generate the GPU tracing information.
The image above is the resulting file (local.trace). There was no GPU data.
It is my system specification.
OS ubuntu 18.04
jupyter-client 5.3.4
jupyter-core 4.6.1
jupyter-tensorboard 0.1.10
tensorflow-gpu 2.0.0
tensorflow-estimator 2.0.1
tensorflow-metadata 0.15.1
tensorboard 2.0.2
nVidia 410.104
CUDA 10.0
anaconda 4.7.12 (with python 3.6)
It looks irrelevant, but there was a warning message like the image below.
I have tested this on other PC and got the same resulting. It could be the GPU profiling is only supporting on Google Colab. (I am still confusing) Recently, I have searched it on google to fix the problem. I could not get still the answer.
Is there someone who is using GPU profiling on your own System instead of Google Colab?
Please give me piece of advices.
I figured out what caused the problem.
It was related with CUPTI(CUDA Profiling Tools Interface)
In contrast to Jupyter Notebook, there was a warning message when the code is running on Ubunto shell.
CUPTI error: CUPTI could not be loaded or symbol could not be found.
TF could not find CUPTI libraries. This is the main reason of the problem.
After adding the path to LD_LABRARY_PATH as below link, the problem is fixed!

I'm trying to run a GitHub code, using TensorFlow 1.x.
I'm using colab for this. I'm encountering this kind of problem which I can't find a solution to.
I'm using Tensorflow 1.15, my Cuda version installed is 10.1 and the Nvidia drive version in colab is NVIDIA-SMI 450.51.05 Driver Version: 418.67.
When I tried to run another code above , cuda seems to be functional.
I'm using the GPU mode on colab
Can someone help me, please?
Thanks.
maybe the notebook session didn't connect the gpu, try restarting the session and wait for notebook to allocate the required resources.
Please share the link of Colab as I think you are not configuring the colab to use the GPUs. You can also follow the steps as,
Go to Colab
In the edit option at upper left corner
In the Hardware accelerator dropdown menu, select GPU.
I make a Project using TensorFlow Object detection.
Windows might have encountered an error because of the GPU module version. Linux is trying again now.
If you look at some review posts, it seems that GPU version has not been used. Is that right?
Doing a course in Machine Learning and can't get Tensorboard to work. I have saved runs from running a DQN and I write:
tensorboard -logdir runs
With the folliwng result:
2019-12-28 18:32:04.265065: I tensorflow/core/platform/cpu_feature_guard.cc:140] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 FMA
TensorBoard 1.7.0 at http://david-linux:6006 (Press CTRL+C to quit)
So I click the link and get:
No dashboards are active for the current data set.
Probable causes:
You haven’t written any data to your event files
TensorBoard can’t find your event files.
I also get this result after having the code running for a while:
"W1228 18:34:34.186506 Thread-2 application.py:272] path /[[_dataImageSrc]] not found, sending 404
W1228 18:34:34.205581 Thread-2 application.py:272] path /[[_imageURL]] not found, sending 404"
Running this on Linux using Anaconda Python version 3.6 because that is what the course book uses. Have no idea what the above errors means, quite new to coding in general and reinforment learning in particular.
It could be caused if the browser isn't updated. You could also try installing the latest version of Tensorboard:
pip uninstall tensorflow-tensorboard
pip install tensorboard
Also try using different browsers.
Can you just try going to http://localhost:6006 instead? It looks like your hostname is not one that actually resolves in DNS.
The GPU version of Tensorboard is having certain issues in Colab although the CPU version works alright. I could not find much from the docs though. This is the error
Also, I tried the following for installation
As you can see, I tried with both GPU and non-GPU versions and it does not work till I disable the GPU from runtime. Any help shall be appreciated.
Is it possible to run Tensorboard on a machine without CUDA support?
I'm working at a computation center (via ssh) which has two major clusters:
CPU-Cluster which is a general workhorse without CUDA support (no dedicated GPU)
GPU-Cluster with dedicated GPUs e.g. for running neural networks with tensorflow-gpu.
The access to the GPU-cluster is limited to Training etc. such that I can't afford to run Tensorboard on a machine with CUDA-support. Instead, I'd like to run Tensorboard on the CPU-Cluster.
With the TF bundled Tensorboard I get import errors due to missing CUDA support.
It seems reasonable that the official Tensorboard should have a mode for running with CPU-only. Is this true?
I've also found an inofficial standalone Tensorboard version (github.com/dmlc/tensorboard), does this work without CUDA-support?
Solved my problem: just install tensorflow instead of tensorflow-gpu.
Didn't work for me for a while due to my virtual environment (conda), which didn't properly remove tensorflow-gpu.
Tensorboard is not limited by whether a machine has GPU or not.
And as far as I know, what Tensorboard do is parsing events pb files and display them on web. There is not computing, so it doesn't need GPU.
