Torch not compiled with cuda enabled windows

I'm trying to do neural style swapping, and for some reason, I keep getting the following errors. AssertionError: Torch not compiled with CUDA enabled File "c:appsMiniconda3libsite-pac...

I had the same problem but still I cannot find a solution to my problem

I installed everything in my anaconda environment with:

conda install -c conda-forge -c pytorch python=3.7 pytorch torchvision cudatoolkit=10.1 opencv numpy pillow

Now I noticed that I installed the following packages (among others)

  python             conda-forge/linux-64::python-3.7.12-hb7a2778_100_cpython
  python_abi         conda-forge/linux-64::python_abi-3.7-2_cp37m
  pytorch            conda-forge/linux-64::pytorch-1.10.0-cpu_py37hf3cc979_0
  pytorch-cpu        conda-forge/linux-64::pytorch-cpu-1.10.0-cpu_py37h718b53a_0
  qt                 conda-forge/linux-64::qt-5.12.9-hda022c4_4

Which means that the versions of pytorch installed are CPU only. Correct?

How can I install now a version of pytorch which is CUDA enabled?

Build cuda_11.5.r11.5/compiler.30672275_0

my is V11.5

then go here and select your os and preferred package manager(pip or anaconda), and the cuda version you installed, and copy the generated install command, I got:

pip3 install torch==1.10.1+cu113 torchvision==0.11.2+cu113 torchaudio===0.10.1+cu113 -f https://download.pytorch.org/whl/cu113/torch_stable.html

notice that for me I had python 3.10 installed but my project run over 3.9 so either use virtual environment or run pip of your wanted base interpreter explicitly (for example C:SoftwarePythonPython39python.exe -m pip install .....)
else you will be stuck with Could not find a version that satisfies the requirement torch errors

then open python console and check for cuda availability

>>> import torch
>>> torch.cuda.is_available()
True

AssertionError: torch not compiled with Cuda enabled error occurs because of using cuda GPU enable syntax over normal PyTorch (CPU only ). There are multiple scenarios where you can get this error. Sometimes CUDA enablement is clear and visible. This is easy to fix by making it false or removing the same. But in some scenarios, It is indirectly calling Cuda which is explicitly not visible. Hence There we need to understand the internal working of such parameter or function which is causing the issue. Anyways in this article, we will go throw the most common reasons.

Solution 1: Switching from CUDA to normal version  –

Usually while compiling any neural network in PyTorch, we can pass cuda enable. If we simply remove the same it will remove the error. Refer to the below example, If you are using a similar syntax pattern then remove Cuda while compiling the neural network.

from torch import nn
net = nn.Sequential(
    nn.Linear(18*18, 80),
    nn.ReLU(),
    nn.Linear(80, 80),
    nn.ReLU(),
    nn.Linear(80, 10),
    nn.LogSoftmax()
).cuda()

The correct way is –

assertionerror torch not compiled with cuda enabled solution

assertionerror torch not compiled with cuda enabled solution

Solution 2: Installing cuda supported Pytorch –

See the bottom line is that if you are facing such an incompatibility issue either you adjust your code according to available libraries in the system. Or we install the compatible libraries in our system to get rid of the same error.

You may any package managers to install cuda supported pytorch. Use any of the below commands –

conda –

conda install pytorch==1.11.0 torchvision==0.12.0 torchaudio==0.11.0 cudatoolkit=11.3 -c pytorch

pip –

pip install torch==1.11.0+cu113 torchvision==0.12.0+cu113 torchaudio==0.11.0 --extra-index-url https://download.pytorch.org/whl/cu113

Solution 3:  set pin_memory=False –

This is one of the same categories where CUDA is not visible directly. But Internally if it is True then it copies the tensors into CUDA space for processing. To Avoid the same we have to make it False. Once more thing, By Default it is True. Hence we have to explicitly make it False while using the get_iterator function in DataLoader class.

torch not compiled with cuda enabled ( Similar Error )-

There are so many error which has similar solution but because of the specification added it looks bit different. Hence to avoid the confusion , Here are some variations:

  1. Platform specification : This error has generic solution with most of the platform like win10, mac, linux etc.
  2. Addition Module : Some time we get this error in intermediate module like detectron2 etc. But the solution will be generic in all the cases.

Benefits of CUDA with Torch –

CUDA is parallel processing framework which provide application interface to deal with graphic card utility of the system. In complex operation like deep learning model training where we have to run operations like backpropagation we need multiprocessing. GPU provide great support for multiprocessing for that we need CUDA (NVIDA ). PyTorch or Tensorflow or any other deep learning  framework required GPU handling for high performance. Although it works fine with CPU in case of small dataset , less epochs etc. But Typically the dataset for any state of art algorithm is usually large in volume. Hence we need CUDA with PyTorch ( Python binding of Torch).

In this article we will see the code solutions for Pytorch assertionerror torch not compiled with cuda enabled.

Why this error occurs?

Cuda is a toolkit which allows GPU to take charge of applications and increase the performance. In order to work with it, it’s essential to have Cuda supported Nvidia GPU installed in your system. Also Pytorch should also support GPU acceleration.

This assertionerror occurs when we try to use cuda on Pytorch version which is for CPU only. So, you have two options to resolve this error –

  1. Use Pytorch version which is compatible to Cuda. Download right stable version from here.
  2. Disable Cuda from your code. This could turn out to be tricky as you might not be using Cuda directly but some of the library in your project may. So, you need to troubleshoot that.

Error Code – Let’s first reproduce the error –

1. cuda passed as function parameter

import torch

my_tensor = torch.tensor([[1, 2, 3], [4, 5, 6]], dtype=torch.float32, device="cuda")
print(my_tensor)

The above code will throw error – assertionerror: torch not compiled with cuda enabled. Here is the complete output –

Traceback (most recent call last):
  File "C:/Users/aka/project/test.py", line 3, in <module>
    my_tensor = torch.tensor([[1, 2, 3], [4, 5, 6]], dtype=torch.float32, device="cuda")
  File "C:Usersakaanaconda3envsdeeplearninglibsite-packagestorchcuda__init__.py", line 166, in _lazy_init
    raise AssertionError("Torch not compiled with CUDA enabled")
AssertionError: Torch not compiled with CUDA enabled

This is because we set the flag device="cuda". If we change it to cpu like device="cpu" then the error will disappear.


2. Dependency using pytorch function with cuda enabled

There are many pytorch functions which copy data to Cuda memory for faster performance. They are generally disabled by default but some dependency of your project could be using those functions and enabling them. So, you need to look into that dependency and disable from there.

For example, torch.utils.data.DataLoader class has parameter pin_memory which, according to pytorch documentation says –

pin_memory (bool, optional) – If True, the data loader will copy Tensors into device/CUDA pinned memory before returning them. 

If a function using this class and setting pin_memory=true, then we will get torch not compiled with cuda enabled error.


Solutions

1. Check Pytorch version

First of all check if you have installed the right version. Pytorch is available with or without Cuda.

PyTorch versions with and without CUDA

2. Check if Cuda is available in installed Pytorch

Use this code to check if cuda is available in your installed Pytorch –

print(torch.cuda.is_available())

3. Create new project environment

Due to a lot of troubleshooting and error handling to resolve bugs, we break our project environment. Try creating a new environment if it solves your Cuda error.

4. Using .cuda() function

Some pytorch functions could be run on GPU by passing them through .cuda(). For example, neural network sequential() function could be run on cuda. So, append or remove it according to your use case –

model = nn.Sequential(OrderedDict([
          ('conv1', nn.Conv2d(1,20,5)),
          ('relu1', nn.ReLU()),
          ('conv2', nn.Conv2d(20,64,5)),
          ('relu2', nn.ReLU())
        ])).cuda()

5. Provide correct device parameter

If a function expects a device parameter then you may provide cuda or cpu according to your use case –

import torch

my_tensor = torch.tensor([[1, 2, 3], [4, 5, 6]], dtype=torch.float32, device="cpu")

print(my_tensor)

I figured out this is a popular question, but still I couldn’t find a solution for that.

I’m trying to run a simple repo Here which uses PyTorch. Although I just upgraded my Pytorch to the latest CUDA version from pytorch.org (1.2.0), it still throws the same error. I’m on Windows 10 and use conda with python 3.7.

    raise AssertionError("Torch not compiled with CUDA enabled")

1) Solution

you dont have to install it via anaconda, you could install cuda from their website. after install ends open a new terminal and check your cuda version with:

>>> nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2021 NVIDIA Corporation
Built on Thu_Nov_18_09:52:33_Pacific_Standard_Time_2021
Cuda compilation tools, release 11.5, V11.5.119
Build cuda_11.5.r11.5/compiler.30672275_0

my is V11.5

then go here and select your os and preferred package manager(pip or anaconda), and the cuda version you installed, and copy the generated install command, I got:

pip3 install torch==1.10.1+cu113 torchvision==0.11.2+cu113 torchaudio===0.10.1+cu113 -f https://download.pytorch.org/whl/cu113/torch_stable.html

notice that for me I had python 3.10 installed but my project run over 3.9 so either use virtual environment or run pip of your wanted base interpreter explicitly (for example C:SoftwarePythonPython39python.exe -m pip install .....)
else you will be stuck with Could not find a version that satisfies the requirement torch errors

then open python console and check for cuda availability

>>> import torch
>>> torch.cuda.is_available()
True
2) Solution

How did you install pytorch? It sounds like you installed pytorch without CUDA support. https://pytorch.org/ has instructions for how to install pytorch with cuda support.

In this case, we have the following command:

conda install pytorch torchvision cudatoolkit=10.1 -c pytorch

OR the command with latest cudatoolkit version.

3) Solution

Uninstalling the packages and reinstalling it with pip instead solved it for me.

1.conda remove pytorch torchvision torchaudio cudatoolkit

2.pip3 install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu116

4) Solution

try this:

conda install pytorch torchvision cudatoolkit=10.2 -c pytorch
5) Solution

This error is happening because of incorrect device. Make sure to run this snippet before every experiment.

device = "cuda" if torch.cuda.is_available() else "cpu"
device
6) Solution

First activate your environment. Replace <name> with your environment name.

conda activate <name>

Then see cuda version in your machine. To see cuda version:

nvcc --version

Now for CUDA 10.1 use:

conda install pytorch==1.4.0 torchvision==0.5.0 cudatoolkit=10.1 -c pytorch

For CUDA 10.0 use:

conda install pytorch==1.4.0 torchvision==0.5.0 cudatoolkit=10.0 -c pytorch

For CUDA 9.2 use:

conda install pytorch==1.4.0 torchvision==0.5.0 cudatoolkit=9.2 -c pytorch
7) Solution

One more thing to note here is if you are installing PyTorch with CUDA support in an anaconda environment, Please make sure that the Python version should be 3.7-3.9.

conda install pytorch torchvision torchaudio cudatoolkit=11.6 -c pytorch -c conda-forge.

I was getting the same «AssertionError: Torch not compiled with CUDA enabled» with python 3.10.

Comments Section

@merv just added. Yeah idk why it says py3.7_cpu_1 for pytorch! ^_^

Maybe try forcing the CUDA version: conda install -c pytorch pytorch=1.2.0=py3.7_cuda92_cudnn7_1 or browse the files for a different compatible version.

That command will reconfigure your environment to use the specified version. So you don’t need to explicitly uninstall. Another (cleaner) option is to create a new env: conda create -n your_env_name -c pytorch pytorch=1.2.0=py3.7_cuda92_cudnn7_1.

Oh. Sorry, I was under the impression that you had a GPU. So, you can forget what I had proposed. You’ll need to switch back to CPU only conda install -c pytorch pytorch=1.2.0=py3.7_cpu_1. I’m not totally sure about this, but I think you need to edit the code in the repo you’re trying to run to explicitly use the CPU, e.g., replacing things like model.cuda() with model.cpu() (see here). But again, this is just my guess.

Sorry, IDK exactly. My strategy would be first changing all cuda() calls to cpu(), then letting it run and debugging where it breaks. I don’t think I can help beyond that generic advice.

Please ask questions in comments only. Answer a question only when you are sure!

nvidia-smi gives me CUDA Version: 11.4 while nvcc --version gives me Cuda compilation tools, release 10.1, V10.1.243. What should I do in this case?

Thank you!! This solution worked for me to enable CUDA on Windows 10 / Conda.

@desmond13 nvidia-smi and nvcc —version report different things, a mismatch doesn’t mean you don’t have required versions. Please read this stackoverflow.com/questions/53422407/…

Isn’t CUDA backwards compatible? If so it shouldn’t matter what version of CUDA driver I have installed as long as its the latest right?

The website gave me pip3 install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu116, but cuda.is_available() still returns False and my script keeps raising AssertionError: Torch not compiled with CUDA enabled.

Make sure you pip installed on the same python interpreter(version) your python project is running on

Вопрос:

Я пытаюсь запустить код из этого репозитория, и мне нужно использовать Pytorch 1.4.0. Я установил версию pytorch только для процессора pip install torch==1.4.0 cpu torchvision==0.5.0 cpu -f https://download.pytorch.org/whl/torch_stable.html .

Я запустил программу, выполнив py -m train_Kfold_CV --device 0 --fold_id 10 --np_data_dir "C:UsersusernameOneDriveDesktopemadeldeenAttnSleepprepare_datasetsedf_20_npz" , но я получаю эту ошибку:

   File "C:UsersusernameAppDataLocalProgramsPythonPython37librunpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "C:UsersusernameAppDataLocalProgramsPythonPython37librunpy.py", line 85, in _run_code

  File "C:UsersusernameAppDataLocalProgramsPythonPython37libsite-packagestorchcuda__init__.py", line 94, in _check_driver
    raise AssertionError("Torch not compiled with CUDA enabled")
AssertionError: Torch not compiled with CUDA enabled
 

Я изменил количество GPU в конфигурации на 0 и попытался добавить device = torch.device('cpu') в начале программы, но это ничего не дает. Как я могу исправить эту ошибку? Я использую Windows 10 с python 3.7.9, если это поможет

Спасибо

Ответ №1:

Вы используете только процессор pytorch, но в вашем коде есть оператор, подобный cr = nn.CrossEntropyLoss(weight=torch.tensor(classes_weights).cuda()) тому, который пытается переместить тензор на графический процессор.

Чтобы исправить это, удалите все .cuda() операции.
