Found CUDA 9.0 but the ZED SDK requires 8.0 #26

Closed klnsz closed 6 years ago

klnsz commented 6 years ago

Hi. I am on jetson tx2 with jetpack 3.2. This version of jetpack comes with cuda 9 but when i try to install zed sdk 2.3 version i got an error saying that "Found CUDA 9.0 but the ZED SDK requires 8.0". Isn't this version of zed sdk comes with a support of cuda 9 or am i missing something?

Anyone has ideas? Thanks

Hi, The ZED SDK 2.3.0 doesn't currently support the jetpack 3.2 (still in developer preview), and therefore only support Cuda 8 on jetson (jetpack 3.1).

However, we plan to release an update for this.

I noticed that on the stereolabs website there is now an option to download "ZED SDK for Jetson TX2 v2.3 (Jetpack 3.2, CUDA 9)". I just tried installing the SDK on my TX2 using Jetpack 3.2 and the installation completed successfully.

However, when I try to run any of the ZED tools, I get the error: error while loading shared libraries: libzstd.so.0: cannot open shared object file: No such file or directory

Doing a quick search, I found libzstd.so.1 and libzstd.so under /usr/local/lib, but not libzstd.so.0. I'm not sure if this is an issue with my setup or an issue with the newest ZED SDK release.

Hi, Yes I forgot to mention that we released the ZED SDK 2.3.0 for the Jetpack 3.2 (Cuda 9)

@sethmnielsen for your issue, a simple sudo apt install libzstd0 should fix the problem. There might be a small bug in the installation script.

@sethmnielsen we released a fix for this issue, ZED SDK 2.3.0b for Jetpack 3.2

sethmnielsen commented 6 years ago

Beautiful. The fix worked! I have the ZED running on a TX2 with Jetpack 3.2 and CUDA 9.0.

Thank you so much for the extremely fast response and fix! Stereolabs rocks!

Doesn't look like you posted this fix for the TX1. Where can I find it?

To clarify, the Jetpack for TX1 has been updated to 3.2 with CUDA 9.0 as well but there is no download for Zed SDK on the TX1 that supports CUDA 9.0. I've tried running both CUDA 8.0 and 9.0 side by side but none of the Zed examples seem to work.

@avirtuos The support for the new Jetpack 3.2 for TX1 will be included in the upcoming version of the ZED SDK (2.4.0).

avirtuos commented 6 years ago

Which will be released when? Even a rough ETA will help me understand if o should go find an alternative for my short term needs. Thanks.

adujardin commented 6 years ago

It should be released in a few weeks.

mfilipen commented 6 years ago

we are looking forward to release, thanks.

croadfeldt commented 6 years ago

Any updates on when the ZED SDK 2.4.0 is due out?

joshuayuan commented 6 years ago

I am also running into this original issue, and am excited for the upcoming update!
