Purpose of window .exe files available in the download list

I see that Cudnn for Cuda 11.x has some additional files versus cuda 10.x

These files are twice smaller than the zipped SDKs, is it just a matter of using a better compression algorithm?

cuDNN offers two methods of install for the Windows platform. The first is through a Zip file of the library, as detailed in the install steps here: Installation Guide :: NVIDIA Deep Learning cuDNN Documentation
The second is through an executable installer (The EXE files that you have mentioned). Both methods are equivalent.

As for the size of the executables, that is due to compression (quite good compression it seems).


Hey Mr @jhalabi !
you just stated that the ZIP and EXE installation methods are equivalent right?

If so, then could you please tell me - FOR GOD’S SAKE - why does the ZIP instructions say to unzip cuDNN files in the following directories…

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\vx.x\bin
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\vx.x\include
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\vx.x\lib\x64

while instead the EXE installer will install them in

C:\Program Files\NVIDIA\CUDNN\v8.3\bin
C:\Program Files\NVIDIA\CUDNN\v8.3\include
C:\Program Files\NVIDIA\CUDNN\v8.3\lib

…thus making cuDNN unfindable by other program requiring them at expecting them at their default location?

Also, would you please explain me WHY ON EARTH when the EXE installer gets to the “Select installation location” it will not allow me to pick a location, and at the same time it will not even care to tell me where it has decided to install the files? Why, after that, I can only click “Finished”? With not even the smallest piece of information regarding where the files have been placed?
Like, do you actually enjoy creating frustration to other people ???

I would bet $ 1000 dollars that almost anyone who came to Nvidia website to install CUDA & cuDNN get sucked up in this insanely stupid flow of events:

  • they install CUDA using the EXE
  • they go on and also download the EXE for cuDNN, rather than the ZIP, thinking that again it would be more immediate
  • then they try using some program requiring cuDNN and they find out cuDNN files are not where they are expected to be
  • then they start looking for where they’ve actually been installed
  • then they end up reinstalling cuDNN using the ZIP file, after wasting so much time after this mess you created!

Another example: the step where it says to install the ZLIB package.
You don’t even tell me what ZLIB is ? Why do I need it ? Where I should extract it ?
But hey, you proceed to explain me that if the download doesn’t start, then I should right click on it and click “Save as”… Like, I’m installing some bloody ML libraries… I think I’m supposed to know how to download a file, what you think??
Why are you just adding noise to the confused and misleading information you already manage to pack up?

Anyway, sure, call this a rant … but … know what? I’m really so confident that it would only take one responsible employee at Nvidia to notice this, and it would only be a matter of time before some others there will find themselves without a good job anymore…

Hello @jhalabi could you please let me know where I can find the compressed exe for more recent builds of Cudnn?
Thanks in advance
