For #4518 from torch._C import * (ImportError: DLL load failed: The specified module could not be found

solution.md

It was caused by the missing of some of the dependencies: mkl, mkl-fft, intel-openmp and VC 2017 Redist.

For conda packages:

conda install mkl mkl-fft intel-openmp numpy
# If package not found, do this
conda update conda

For wheel packages:

pip install mkl mkl-fft intel-openmp numpy

And then download VC 2017 Redist and install it.

A reboot may be required for the libraries to take effect.

If this persists, it may be related to your environmental variables, such as PATH. Make sure it is not broken and at least point to the following locations:

[PythonRoot]
[PythonRoot]\Library\bin
[PythonRoot]\Scripts
[PythonRoot]\bin
%SYSTEMROOT%

P.S: #7579 ImportError: DLL load failed: The operating system cannot run %1. does not seem to be the same issue with this. It is related to Anaconda. Fix command: conda install -c defaults intel-openmp -f. If you want to help us, please provide us the logs with python -v -c 'import torch' and the result of the following code:

# pip install psutil first
import psutil, os
p = psutil.Process( os.getpid() )
for dll in p.memory_maps():
  print(dll.path)

These instructions worked for me; it seemed that the environment variables were the issue for me. Thanks a lot!

ImportError: DLL load failed: The specified module could not be found.
since i am using windows 10 ..pls help with reliable answer

@peterjc123 I found that this error, from torch._C import * (ImportError: DLL load failed: The specified module could not be found, rises when I installed Pytorch outside the base environment (using anaconda). But, when I installed Pytorch in the base/main environment, all are okay.
I guess that because only the base environment is included in PATH variable. i.e.

[PythonRoot]
[PythonRoot]\Library\bin
[PythonRoot]\Scripts
[PythonRoot]\bin

where PythonRoot=Anaconda3, (main anaconda directory).

I don't know what's wrong with anaconda.

@sykrn: It seems like the problem is related to the python version that gets installed in your conda environment. I belief base ships with 3.7.1 and this version works with pytorch.

See this issue here and this issue here for more information. The pytorch team is currently implementing a fix from what I read:)

I have tackled this by creating a full conda environment with anaconda installed in it.
Pl. have a look on my answer here at stackoverflow: https://stackoverflow.com/a/54742569/9071644

I have same issue and below are my specs.
System = Windows 10
Type = X64 and CPU only
Python Ver = 3.6
Installation = pip

I have already installed the mkl and mkl-fft intel-openmp and numpy using pip

I think you should try conda distro the steps are provided here:
1:) conda create -n pyTorchCPU python=3.6 urllib3
2:) conda activate pyTorchCPU
3:) conda activate numpy matplotlib mkl mkl_fft
4:) conda install pytorch-cpu torchvision-cpu -c pytorch
5:) python -c "import numpy; import torch"

This procedure worked for me:
1:) conda create -n pyTorch python=3.6 urllib3
2:) conda activate pyTorch
3:) pip install numpy mkl mkl-fft
4:) pip install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp36-cp36m-win_amd64.whl
5:) pip install torchvision
6:) python -c "import numpy; import torch; print(torch.version)"

@sykrn: It seems like the problem is related to the python version that gets installed in your conda environment. I belief base ships with 3.7.1 and this version works with pytorch.

Okay, that's good news, thanks @harlecin
