Backend rendering disabled on 7.0.0

Hello,
On a 20.04 Ubuntu with free EE GPU Heavyai in Docker with Jupyter and a GTX1080 8GB system, the GEO CHOROPLETH charts that worked fine in V. 6.4.0 started to return the message:

and this in the error log (forward compatibility was attempted on non supported HW ???? )

2023-05-12T11:49:15.435316 E 28 0 0 DBHandler.cpp:531 Unable to instantiate CudaMgr, falling back to CPU-only mode. CUDA Error (804): forward compatibility was attempted on non supported HW

What is happening here?

In addition in the choropleth chart I can't see anymore my personalized geo json despite I stil have my personalized tables available and I think, correctly migrated to V.7

Hi Gianfranco,

About the first error, the new release needs the NVIDIA 520.61.05 (CUDA 11.8) or greater drivers installed, so the with 515 is going to fall back to CPU mode.

In the case of Choropleth in CPU mode you have to include the geojson in immerse itself like we did in this post

https://support.heavy.ai/hc/en-us/community/posts/10752360682647-Maps-on-the-Mac

but it's better using the GPU Choropleth charts, that should pop-up when the new driver will be installed

Regards,

Candido.

In addition I tryied to re-import the geo tables with the commad:

COPY comuni_simp FROM '/var/share/ingesting/ComuniWGS84.geojson' WITH (source_type='geo_file');

The table get created correctly, but I still can't see it in the GEOJSON selection for the choropleth chart:

Excellent,

all is working fine in GPU mode after upgrading to CUDA 12 and NVIDIA 530, the geojsons popped out soon after the new drivers installation as you predicted: thank you Candido.

I'm just wondering if this info is included in some online docs page on the website: I couldn't find it.

Anyway, I will add this in my HeavyAI upgrading tricks list.

Hi Gianfranco,

Which info are you referring to?

The software requirements are listed in the docs
https://docs.heavy.ai/installation-and-configuration/system-requirements/software-requirements

Or are you referring to geojson stuff?

Regards,
Candido.

I was referring exactly to the info you linked in the the software requirements page:

I missed that, so my bad !

Thank you for pointing me quickly to the solution, I removed that from the trick list, and added to the upgrading check list ! ^_^
