CalendulaED · 2020-09-13T22:01:41Z

I got this issue when I run import tensorflow as tf in command line

import tensorflow as tf
2020-09-13 17:53:34.644899: W tensorflow/stream_executor/platform/default/dso_loader.cc:59] Could not load dynamic library 'cudart64_101.dll'; dlerror: cudart64_101.dll not found

I use win10 and install the CUDA and cuDNN
But I don't understand why this still happened.

bhack · 2020-09-13T22:04:23Z

Please pip install tf-nightly for CUDA 11

CalendulaED · 2020-09-13T22:08:48Z

After I tried pip install tf-nightly, it still shows the same error I think

bhack · 2020-09-13T22:13:22Z

Is not the same error cause now it is looking for 110.

Are you compilant with these steps?

Install the Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017, and 2019. Starting with the TensorFlow 2.1.0 version, the msvcp140_1.dll file is required from this package (which may not be provided from older redistributable packages). The redistributable comes with Visual Studio 2019 but can be installed separately:

Go to the Microsoft Visual C++ downloads,

Scroll down the page to the Visual Studio 2015, 2017 and 2019 section.

Download and install the Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 for your platform.

Make sure long paths are enabled on Windows.

Install the 64-bit Python 3 release for Windows (select pip as an optional feature).

bhack · 2020-09-13T22:14:53Z

You will find more on Windows tabs at https://www.tensorflow.org/install/pip#windows

I think the problem is solved after I Download and install the Microsoft Visual C++ Redistributable.
Thank you so much !

bhack · 2020-09-13T22:23:23Z

You need also to rely on tf-nightly for CUDA 11 untill TF 2.4 is released.

CalendulaED · 2020-09-13T22:26:07Z

I tried to use the example given by https://github.com/tensorflow/tensorflow
after I run the tf.add(1, 2).numpy()
it still shows some errors but evenlty output the 3
will this be a problem?

bhack · 2020-09-13T22:31:01Z

Check that your software requirements are ok https://www.tensorflow.org/install/gpu#windows_setup

CalendulaED · 2020-09-13T23:11:06Z

Check that your software requirements are ok https://www.tensorflow.org/install/gpu#windows_setup

I think I have everything it required.
And after I update my GPU driver, it shows the same error as the beginning.

bhack · 2020-09-13T23:21:19Z

Have you double checked the %PATH%?

CalendulaED · 2020-09-14T00:08:54Z

Have you double checked the %PATH%?

I run all four Path in https://www.tensorflow.org/install/gpu#windows_setup.
But it still missing for 110

bhack · 2020-09-14T00:12:01Z

Have you changed the documentation PATH strings for your CUDA 11 (doc has CUDA 10)?
Have you checked that these paths exist on your system?

CalendulaED · 2020-09-14T00:14:39Z

Have you changed the documentation PATH strings for your CUDA 11 (doc has CUDA 10)?
Have you checked that these paths exist on your system?

Yes, I manually added it for the first three, but the last one "C:\tools\cuda\bin", I don't think I have this folder

CalendulaED · 2020-09-14T00:23:51Z

At the beginning, I copy the cuDNN's file to bin include and lib respectively, I tried to add a Path directly to cuDNN and it is still having this error

bhack · 2020-09-14T00:26:26Z

Have you set in PATH
SET PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11\bin;%PATH%

Do you have this dir in your system?

CalendulaED · 2020-09-14T01:07:47Z

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11\bin

Yes, and I already added to the path, but it still shows the error

CalendulaED · 2020-09-14T01:11:41Z

This is all the PATH I have, I think I already include all that required

bhack · 2020-09-14T01:17:09Z

Open C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11\bin.
What file do you have there?
Can you see the cudart64_100.dll?

CalendulaED · 2020-09-14T01:19:45Z

I think I only have cudart64_110.dll
(The one that I highlighted)

bhack · 2020-09-14T01:36:26Z

Yes was a typo It is correct.
On the same terminal where you are trying to launch Tensorflow can you verify that you have the new path with echo %PATH:;=&echo.%?

CalendulaED · 2020-09-14T01:38:57Z

Yes, I believe I have this path in PATH

bhack · 2020-09-14T01:45:45Z

I see a typo there:
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11\bin\bin

CalendulaED · 2020-09-14T01:47:44Z

I see a typo there:
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11\bin\bin

Yes, It is the path to cuDNN, After I download the cuDNN, I copy the bin in cuDNN to here.
I have both:
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11\bin\bin
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11\bin

Before I add the
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11\bin\bin
it still doesn't work, so I tired to add it

CalendulaED · 2020-09-14T01:52:03Z

And I delete it from PATH, it still has the same error

bhack · 2020-09-14T01:58:07Z

Do you meant v11.0 or v11?

CalendulaED · 2020-09-14T02:02:03Z

Do you meant v11.0 or v11?

I mean v11.0, I delete the one ~/bin/bin
but it is still not working

bhack · 2020-09-14T02:05:39Z

Is a python 64bit installation?

bhack · 2020-09-28T23:04:16Z

Nothing specific is to maintain a clean separate environment.

CalendulaED · 2020-09-28T23:05:18Z

Nothing specific is to maintain a clean separate environment.

Ok, thank you so much!!!! really help me a lots

caxelrud · 2020-10-02T02:29:41Z

I have to renamed these files in the bin folder to make it work:
cudart64_101.dll -> cudart64_110.dll
cusparse64_10.dll->cusparse64_11.dll
cudnn64_7.dll->cudnn64_8.dll
cublas64_10.dll->cublas64_11.dll

caxelrud · 2020-10-02T03:54:29Z

The reality is that each version of Tensorflow uses an specific Cuda and Cudnn. In my case, for TF 2.3 it is Cuda 11.0. Installing this one solves the problem.

magpayang · 2020-11-22T11:27:05Z

I have to renamed these files in the bin folder to make it work:
cudart64_101.dll -> cudart64_110.dll
cusparse64_10.dll->cusparse64_11.dll
cudnn64_7.dll->cudnn64_8.dll
cublas64_10.dll->cublas64_11.dll

also encountered cusolver64_10.dll not found. when I checked the bin folder, it is named as cusolver64_11.dll

aparico · 2020-12-22T10:17:21Z

I was able to solve this by following the software requirements here: https://www.tensorflow.org/install/gpu#software_requirements

Here's my system:
NVIDIA Driver 460.89
CUDA 11.0.3
CuDNN 8.0.5.39
Python 3.7.2

I also made sure that the CUDA was compatible with the CuDNN version by checking it here: https://developer.nvidia.com/rdp/cudnn-download

Finally, don't forget to set the installation directories to the PATH environment variable. https://www.tensorflow.org/install/gpu#windows_setup

vanc · 2020-12-31T18:25:15Z

The key is to install Python from python.org. All versions from Microsoft App Store don't work. Tried both 3.7, 3.8. Once installed the official version 3.8.7 downloaded from python.org, everything is fine now.

This is my current system:

NVIDIA Driver 460.89
CUDA 11.0.3
CuDNN 8.0.5.39
Python 3.8.7 (from python.org)

I also tried with CUDA 11.1.1. It also worked after renaming cusolver64_11.dll to cusolver64_10.dll. It's a known issue tracked in issue #44291.

GPlaying · 2021-01-17T13:02:23Z

I got a way to solve this problem, you can download cudart64_101.dll to C:\Users\hp and C:\Windows\System32 from
https://www.ijinshan.com/filerepair/cudart64_101.dll.shtml.

Rob192 · 2021-01-21T08:58:56Z

Hello,
Thanks @aparico for the tip ! It did work with this configuration and pip install tensorflow. However, the software versions in the software requirements section of the https://www.tensorflow.org/install/gpu#software_requirements are not correct as they recommand CUDA 10.1 and CuDNN 7.6 and the install works with CUDA 11.0 and CuDNN 8.0.
Maybe this page needs update ?

mefistaa · 2021-06-17T18:28:51Z

CUDA 11.2
cuDNN 8.1
tensorflow 2.5
python 3.9.5
in virtual env write "where cudart64_110.dll" and get path.
when taping "import tensorflow as tf" get:
"W tensorflow/stream_executor/platform/default/dso_loader.cc:64] Could not load dynamic library 'cudart64_110.dll'; dlerror: cudart64_110.dll not found"

Tried to install tf-nightly, tensorflow
I have been installing to main enviroment and to virtual enviroment, in both cases have got the same result.
VC_redist.x64 installed

Solution:

import os
os.add_dll_directory("C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.2/bin")

Before importing tensorflow in virtualenv and still does not work in main env.

OmarJay1 · 2021-07-30T22:38:21Z

Thank you for posting the os.add_dll_directory tip. I believe the behavior is by design for newer versions of Python on Windows. The Windows Path environment variable no longer works. That's what I'm guessing is going on.

https://docs.python.org/3/whatsnew/3.8.html#bpo-36085-whatsnew

Specifically, PATH and the current working directory are no longer used, and modifications to these will no longer have any effect on normal DLL resolution.

nuramzan · 2021-09-16T22:47:54Z

I do an easy way to deal with this problem like below :

Install anaconda with python 3.8.8
Install tensor flow : pip install tensorflow -> got an error like above
"W tensorflow/stream_executor/platform/default/dso_loader.cc:59] Could not load dynamic library 'cudart64_110.dll'; dlerror: cudart64_110.dll not found"
Install package -> pip install tf-nightly
Install the Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017, and 2019 -> https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0
Verify the system has a CUDA-capable GPU -> http://developer.nvidia.com/cuda-gpus.
Using Conda to Install the CUDA Software (https://docs.nvidia.com/cuda/cuda-installation-guide-microsoft-windows/) -> conda install cuda -c nvidia
Verify the Installation of CUDA toolkit -> nvcc -v
import tensorflow as tf is succeed, and you are ready to implement deep learning using jupyter notebook
Hope this information is helpful....

BornSupercharged · 2021-09-27T11:44:16Z

I had this error, as well as:
Could not load dynamic library 'cudnn64_8.dll'; dlerror: cudnn64_8.dll not found

Here's what worked for me, with Python 3.9.6 running on my Windows 10 laptop with a mobile RTX 3080.

Upgrade to the latest NVidia drivers:
-- https://www.nvidia.com/drivers

Install CUDA 11.4:
-- https://developer.nvidia.com/cuda-downloads?target_os=Windows&target_arch=x86_64&target_version=10&target_type=exe_local

Install cuDNN 8.2.4 for CUDA 11.4:
-- https://developer.nvidia.com/rdp/cudnn-download
-- choose cuDNN Library for Windows (x64), extract to C:\tools so you have C:\tools\cuda\bin\cudnn64_8.dll

Update your Windows %PATH%, by going to Windows Advanced System Properties -> Environment Variables -> PATH -> New, adding these:
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.4\bin
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.4\extras\CUPTI\lib64
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.4\include
C:\tools\cuda\bin

Download and install the x64 C++ Redistributable:
-- https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0

Download and install the x86 C++ Redistributable:
-- https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0

pip install tensorflow
pip install tf-nightly

Reboot your computer.

Works perfectly now.

lbiemans · 2021-12-16T13:16:43Z

What fixed it for us:

import os
os.add_dll_directory("C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.2/bin") # (Where v11.2 is your version)

twinssbc · 2022-02-27T12:50:59Z

add_dll_directory also works for me. This is due to since Python 3.8, %PATH% is not longer in the dll search path.
https://docs.python.org/3/library/os.html#os.add_dll_directory

RajdeepBorgohain · 2022-03-18T21:35:44Z
