When run:
which nvcc
It says:
nvcc not found
And I did not found clear guide to install nvcc,on macOS catalina 10.15.7.
Because I am trying to run https://github.com/jugg1024/Text-Detection-with-FRCN.git. But on cammand:
make -j16 && make pycaffe:
From here:
It gives this error:
Thats why i do need nvcc installation.
Any assistance you can provide would be greatly appreciated!
Since CUDA 11.0, macOS is not a supported environment for CUDA.
The last supported environment was based on CUDA 10.2 (see here) and a macOS version of 10.13.x
There has never been a supported nvcc install, CUDA install, or CUDA version for macOS 10.15.x
If you don't have a CUDA-capable GPU in your mac, it's not clear why you would want to install nvcc or CUDA. They could possibly be used to build code, but that code wouldn't be runnable on that machine.
If you do have a CUDA capable GPU in your mac, you would want to follow the above linked instructions carefully, noting carefully the machine requirements, such as supported macOS version. CUDA 10.2 would be the latest/last version of CUDA you could install on that mac.
I am working on installing PyTorch from source but am unsure about the specific dependency versions to use for the version of PyTorch I want to install.
In particular, I noticed performance variations depending on the gcc version I use to compile PyTorch. Which compiler should I be using to get the best PyTorch performance?
Tensorflow doc provides such useful information. They call it "Tested build configurations":
https://www.tensorflow.org/install/source#tested_build_configurations.
The README.md has instructions to build from source.
If you are installing from source, you will need a C++14 compiler. Also, we highly recommend installing an Anaconda environment. You will get a high-quality BLAS library (MKL) and you get controlled dependency versions regardless of your Linux distro.
Once you have Anaconda installed, here are the instructions.
If you want to compile with CUDA support, install
NVIDIA CUDA 9 or above
NVIDIA cuDNN v7 or above
Compiler compatible with CUDA
If you want to disable CUDA support, export environment variable USE_CUDA=0. Other potentially useful environment variables may be found in setup.py.
If you are building for NVIDIA's Jetson platforms (Jetson Nano, TX1, TX2, AGX Xavier), Instructions to install PyTorch for Jetson Nano are available here
You can found Latest, official Compiler requirements here
There doesn't seem to be any detailed documentation for how to compile TensorFlow 1.4.0 GPU on Windows 10 x64.
I need to recompile TF to add missing functionality for a Windows 7 x64 production system.
The official Google link at Installing TensorFlow from Sources just says
We don't officially support building TensorFlow on Windows; however,
you may try to build TensorFlow on Windows if you don't mind using the
highly experimental Bazel on Windows or TensorFlow CMake build.
Okay fine, I can use Bazel to try to compile something like
bazel build -c opt --copt=-mavx --copt=-mavx2 --copt=-mfma --copt=-mfpmath=both --config=cuda -k //tensorflow/tools/pip_package:build_pip_package
but how do I incorporate the Python and NVIDIA dependencies into that build?
Should I use CMake instead?
How were the Windows wheels at https://pypi.python.org/pypi/tensorflow-gpu compiled?
Got the answer from Adriano Carmezim over at github. The complete instructions for building TensorFlow on Windows, including making Windows Python wheels are at: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/contrib/cmake/README.md
Additional issues are addressed on github
To build tensorflow on windows use cMake.
Environment:
Windows10
Python 3.5.3 64bit
CUDA Toolkit 8.0
cuDNN v5.1(extracted to Toolkit8.0 files)
Visual Studio Community 2015
Nightly binary#243 Tensorflow GPU version (pip install tensorflow_gpu-1.2.1-cp35-cp35m-win_amd64.whl)
The package has not been installed correctly, and the file _pywrap_tensorflow.pyd is not present in the C:\...\Lib\site-packages\tensorflow\python
After I got nearly the same error as #5949, I tried mrry's tensorflow_self_check.py.
The output is:
ERROR: Failed to import the TensorFlow module.
Python version is 3.5.
TensorFlow is installed at: C:\Python\Python35\lib\site-packages\tensorflow
All required DLLs are present. Please open an issue on the
TensorFlow GitHub page: github.com/tensorflow/tensorflow/issues
However, I can import the tensorflow successfully if I use the below version:
pip install --upgrade https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-0.12.0-cp35-cp35m-win_amd64.whl
So, what's wrong the tensorflow_gpu-1.2.1 version?
I really hope someone can help me solve it completely. Thank you!
I would suggest to use Anaconda for the windows, if you want to try tensorflow. The number of issues is very less.
https://www.tensorflow.org/install/install_windows
But if you really want to work without anaconda.
Check your path to Cuda, Cudnn and python.
Ensure that cudnn is v5.1
TensorFlow 1.3 or later requires cuDNN 6.
Installing the Microsoft Visual C++ 2015 Redistributable Update 3 (x64 version) can fix it.
Do let me know about after trying above steps.
According to
https://www.tensorflow.org/install/install_mac Note: As of version 1.2, TensorFlow no longer provides GPU support on Mac OS X.
GPU support for OS X is no longer provided.
However, I would want to run an e-gpu setup like akitio node with a 1080 ti via thunderbolt 3.
What steps are required to get this setup to work?
So far I know that
disable SIP
run automate e-gpu script https://github.com/goalque/automate-eGPU
are required. What else is needed to get CUDA / tensorflow to work?
I wrote a little tutorial on compiling TensorFlow 1.2 with GPU support on macOS. I think it's customary to copy relevant parts to SO, so here it goes:
If you haven’t used a TensorFlow-GPU set-up before, I suggest first setting everything up with TensorFlow 1.0 or 1.1, where you can still do pip install tensorflow-gpu. Once you get that working, the CUDA set-up would also work if you’re compiling TensorFlow. If you have an external GPU, YellowPillow's answer (or mine) might help you get things set up.
Follow the official tutorial “Installing TensorFlow from Sources”, but obviously substitute git checkout r1.0 with git checkout r1.2.
When doing ./configure, pay attention to the Python library path: it sometimes suggests an incorrect one. I chose the default options in most cases, except for: Python library path, CUDA support and compute capacity. Don’t use Clang as the CUDA compiler: this will lead you to an error “Inconsistent crosstool configuration; no toolchain corresponding to 'local_darwin' found for cpu 'darwin'.”. Using /usr/bin/gcc as your compiler will actually use Clang that comes with macOS / XCode. Below is my full configuration.
TensorFlow 1.2 expects a C library called OpenMP, which is not available in the current Apple Clang. It should speed up multithreaded TensorFlow on multi-CPU machines, but it will also compile without it. We could try to build TensorFlow with gcc 4 (which I didn’t manage), or simply remove the line that includes OpenMP from the build file. In my case I commented out line 98 of tensorflow/third_party/gpus/cuda/BUILD.tpl, which contained linkopts = [“-lgomp”] (but the location of the line might obviously change). Some people had issues with zmuldefs, but I assume that was with earlier versions; thanks to udnaan for pointing out that it’s OK to comment out these lines.
I had some problems building with the latest bazel 0.5.3, so I reverted to using 0.4.5 that I already had installed. But some discussion in a github issue mentioned bazel 0.5.2 also didn’t have the problem.
Now build with bazel and finish the installation as instructed by the official install guide. On my 3.2 GHz iMac this took about 37 minutes.
Using python library path: /Users/m/code/3rd/conda/envs/p3gpu/lib/python3.6/site-packages

INFO: Starting clean (this may take a while). Consider using --async if the clean takes more than several minutes.
Configuration finished
Assuming that you have already setup your eGPU box and attached the TB3 cable from the eGPU to your TB3 port:
1. Download the automate-eGPU script and run it
curl -o ~/Desktop/automate-eGPU.sh
https://raw.githubusercontent.com/goalque/automate-eGPU/master/automate-eGPU.sh
&& chmod +x ~/Desktop/automate-eGPU.sh && cd ~/Desktop && sudo
./automate-eGPU.sh
You might get an error saying:
"Boot into recovery partition and type: csrutil disable"
All you need to do now is to restart your computer and when it's restarting hold down cmd + R to enable the recovery mode. Then locate the Terminal while in recovery mode and type in:
csrutil disable
Then restart your computer and re-run the automate-eGPU.sh script
2: Download and installing CUDA
CUDA: https://developer.nvidia.com/cuda-downloads
Run the cuda_8.0.61_mac.dmg file and follow through the installation phase. Then afterwards you will need to set the paths.
Go to your Terminal and type:
vim ~/.bash_profile
Or whether you have stored your environmental variables and then add these three lines:
export CUDA_HOME=/usr/local/cuda
export DYLD_LIBRARY_PATH="$CUDA_HOME/lib:$CUDA_HOME:$CUDA_HOME/extras/CUPTI/lib"
export LD_LIBRARY_PATH=$DYLD_LIBRARY_PATH
3. Downloading and installing cuDNN
cuDNN: https://developer.nvidia.com/cudnn
To download cuDNN is a bit more troublesome you have to sign up to be a developer for Nvidia and then afterwards you can download it. Make sure to download cuDNN v5.1 Library for OSX as it's the one that Tensorflow v1.1 expects Note that we can't use Tensorflow v1.2 as there is no GPU support for Macs :((
[![enter image description here][1]][1]
Now you will download a zip file called cudnn-8.0-osx-x64-v5.1.tgz, unzip and, which will create a file called cuda and cd to it using terminal. Assuming that the folder is in Downloads
Open terminal and type:
cd ~/Downloads/cuda
Now we need to copy cuDNN files to where CUDA is stored so:
sudo cp include/* /usr/local/cuda/include/
sudo cp lib/* /usr/local/cuda/lib/
4. Now install Tensorflow-GPU v1.1 in your conda/virtualenv
For me since I use conda I created a new environment using Terminal:
conda create -n egpu python=3
source activate egpu
pip install tensorflow-gpu # should install version 1.1
5. Verify that it works
First you have to restart your computer then:
In terminal type python and enter:
import tensorflow as tf
with tf.device('/gpu:0'):
a = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[2, 3], name='a')
b = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[3, 2], name='b')
c = tf.matmul(a, b)
with tf.Session() as sess:
print (sess.run(c))
If you have a GPU this should run with no problem, if it does then you should get a stack trace (just a bunch of error messages) and it should include
Cannot assign a device to node 'MatMul': Could not satisfy explicit device specification '/device:GPU:0' because no devices matching that specification are registered in this process
If not then you're done congratz! I just got mine set up today and it's working perfectly :)
I could finally make it work with the following setup
Hardware
Nvidia Video Card: Titan Xp
EGPU: Akitio Node
MacBook Pro (Retina, 13-inch, Early 2015)
Apple Thunderbolt3 to Thunderbolt2 Adapter
Apple Thunderbolt2 Cable
Software versions
macOS Sierra Version 10.12.6
GPU Driver Version: 10.18.5 (378.05.05.25f01)
CUDA Driver Version: 8.0.61
cuDNN v5.1 (Jan 20, 2017), for CUDA 8.0: Need to register and download
tensorflow-gpu 1.0.0
Keras 2.0.8
I wrote a gist with the procedure:
https://gist.github.com/jganzabal/8e59e3b0f59642dd0b5f2e4de03c7687
Here is my solution to install an e-gpu on a mac. Tensorflow doesn't support tensorflow-gpu anymore, so there are definitely better approaches to get it working:
My configuration:
IMac 27' late 2012
Aktio Node
GTX 1080 ti
3 Screens: One of them connected to the GTX 1080 and the others directly plugged on the mac.
Advantages of windows bootcamp installation:
You can use pip to install tensorflow-gpu.
Good GPU 1080 ti support (Downloadable display driver)
Howto:
Install windows 10 with bootcamp. Do not connect the Akito node for the moment.
Download and install the display driver for your gpu from NVIDIA download page
Install Visual Studio
If you want to use CUDA 9.x you can install Visual Studio 2017
Otherwise install Visual Studio 2015
Install CUDA and CuDNN
Note that the tensorflow-gpu version must match with your Cuda and your CudNN version. See available tensorflow releases here.
After the CUDA installation you can move the unpacked CuDNN files to the CUDA folder at: C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0. Move the lib files to the lib folder, the bin files to the bin folder and the include files to the include folder.
Install Python 3.5+
You need a 64-bit version to install tensorflow-gpu with pip
Python 2.7 won't work.
Install tensorflow with pip:
Command:
pip install tensorflow-gpu==1.5.0rc0
Check your installation
The display driver has been installed correctly when you can plug a screen to the GTX 1080 ti card.
Call C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe to check if your video card is available for CUDA.
Execute the following tensorflow command to see available devices:
from tensorflow.python.client import device_lib
device_lib.list_local_devices()
Troubleshooting and hints:
Windows wants to update your GTX 1080 driver. Never allow that because you
won't be able to startup your computer again! A black screen with moving dots will appear before you can login to windows. Game over! Only use the display driver from NVIDIA download page.
If you cannot start windows on OSX anymore, press the alt key at startup to reinstall windows.
Ubuntu solution:
I couldn't find a working solution but here are some approaches:
It seems that my GTX 680 (iMac) and my GTX 1080 ti won't work together. Ubuntu could not be started anymore after installing the display driver via apt-get: Ubuntu not starting anmore. Try to download the official display driver from NVIDIA download page.
OSX Solution:
Tensorflow GPU is only supported up to tensorflow 1.1. I tried to install a newer version but couldn't build tensorflow-gpu with cuda support. Here are some approaches:
Install OSX Sierra to use the e-gpu script. High Sierra won't work (Jan, 13 2018). Downgrade to sierra by deleting all your partitions. Then press Command + R at startup to load the internet recovery. Don't forget to backup your data first.
Install e-gpu script.
If tensorflow-gpu 1.1 is enough for you, you can just install via pip, otherwise you need to build your pip with bazel.
Conclusion:
The windows installation is easier than OSX or Ubuntu installation because display drivers work properly and tensorflow and must not be build on your own. Always check the software version you use. The must match exactly.
I hope this will help you!
