Unable install Pytorch from source for older GPU card

[Valentas]

Good day,

I want to set up locally fastai environment. However, when I try running the first part of the tutorial, I receive an error message stating:

Found GPU0 GeForce GTX 860M which is of cuda capability 5.0.
PyTorch no longer supports this GPU because it is too old.

I found that the problem is related to Pytorch version, which does not support older GPU cards. I found a solution to install older Pytorch from source: pyTorch not working with an old NVidia card

However, when I clone pytorch git and try to install with install.py, I receive a message error.

python setup.py install
running install
running build_deps
error: [WinError 2] The system cannot find the file specified

I have navigated to the correct folder “~\Fast_AI\Github material\fastai\pytorch”, when I list the files I can see setup.py, but it does not allow to run.

Could anyone help solve this problem? I could use CPU, however, it works very slowly when working with deep learning, therefore I would prefer to use GPU.

Hi,

based on the exception

error: [WinError 2] The system cannot find the file specified

I assume you are on Windows.

I ran into the same problem with a GPU which supports only compute capabilty 3.0, for me the solution was to install a legacy binary build (pytorch-0.3.0) provided by peterjc123 in his Google Drive folder.

Hi joschka,

thank you for the link. Yes I am using windows 10 and python 3.6, with Cuda 8.0. However, my capability is 5.0 since I am using GeForce GTX 860M. I have downloaded the pytorch-0.3.0-py36_0.3.0cu80.tar.bz2.

And it works!

Thank you very much for your help and link to google drive!

The latest version of PyTorch has support for Windows.

Hello,

My OS is Ubuntu 16.04. My GPU is a GeForce GTX 960M.

I am new to conda. How can I replace pythorch with the binaries in the conda environment?

I would appreciate more details,

Thanks,

I think the six steps listed in this section will help you:

pyTorch not working with an old NVidia card

Solved by compiling pyTorch from source. Here is how to do so in details: 1- Activate the virtual env: source activate fastai 2- Uninstall pyTorch conda uninstall pytorch 3- Clone pyTorch repo: git clone --recursive https://github.com/pytorch/pytorch 4- Checkout to the latest branch (so that we install pytorch 0.3.1) cd pytorch git checkout v0.3.1 5- Sort out dependencies (I only needed cmake): git submodule update --init sudo apt install cmake 6- Install, this is were compiling takes…

In my case, when I downloaded the pytorch from local source, I could not manage to install it. Therefore, I downloaded windows installer via Joschka suggestion (see answer above).

Hey,
Thank you so much for your tips on this thread and here as well.

I ended up downloading pytorch-0.3.0-py36_0.3.0cu80.tar.bz2 as well and pasting it inside of the fastai folder. I then ran conda install pytorch-0.3.0-py36_0.3.0cu80.tar.bz2 in the command line. Is this what you did as well? I wasn’t sure if this is a kosher way of doing it.

At any rate, it worked (after hours) hahah.

Thanks

Hi,

Yes I did the same thing, just set the location of the file to my download folder.

Glad to hear that it worked!

[danny93 (Danilo Pena)]

Now I am having a trouble with memory.

Did you download the pytorch folder as stated in the other thread? Or did you just install pytorch-0.3.0-py36_0.3.0cu80.tar.bz2?

[Valentas]

Yes, I downloaded the packaged and installed it via conda prompt to fastai environment.

I do not remember the precise command, but I assume its conda install filename.

Before you can navigate to the location of the file using cd.

After a long search i found the solution
The problem is that if the GPU is old the pytorch version before 0.4.0 doesn’t work, so you have to install the newest pytorch,
run this - conda install -c pytorch pytorch
After you install the newest pytorch you will face torch._C import * DLL load failed problem
to fix that run the ff code
set PYTORCH_BUILD_VERSION=0.4.1

What cuda version do you run CUDA8.x or CUDA9.2?
Whats’ about conda install pytorch cuda92 -c pytorch
pip3 install torchvision

Hi All,
I have windows machine with old GPU 960M
i am having problem with running fastai lesson 1

I get following error
RuntimeError: cuda runtime error (48) : no kernel image is available for execution on the device at c:\anaconda2\conda-bld\pytorch_1519501749874\work\torch\lib\thc\generic/THCTensorMath.cu:15

I tried following steps:

1. i dont know how to install PyTorch 0.4.0
2. i tried this solution (conda install -c peterjc123 pytorch)

nothing is working for me. please help.
thanks

Hi there. I kinda combined the methods from this post and this one for my Windows 10, CUDA 10.0, GTX 950M environment.

I have done the following steps in Anaconda:

1. conda activate fastai
2. conda uninstall pytorch
3. git clone --recursive https://github.com/pytorch/pytorch
4. cd pytorch
5. conda install -c pytorch pytorch

I checked the versions in my Jupyter Notebook by the following code:

import torch
print("PyTorch version: ", torch.__version__)
print("CUDA Version: ", torch.version.cuda)
print("cuDNN version is: ", torch.backends.cudnn.version())

Before the versions for fastai was:

PyTorch version: 0.3.1.post2
CUDA Version: 9.0
cuDNN version is: 7003

Now they are:

PyTorch version: 1.0.0
CUDA Version: 9.0
cuDNN version is: 7005
Device: cuda:0

Then tried the fastai course notebooks. Yep, it worked. The key is the PyTorch version. Thanks, guys.

P.S. My non-fastai environment is like:

PyTorch version: 1.0.0
CUDA Version: 10.0
cuDNN version is: 7401
Device: cuda:0
