Running experiment with C++ algorithm

[Joseph McGrath]

Hi,

I'm seeing this error 

When I attempt to run the experiment jmcgrat3/livdet-baseline/1.

The .so file exists and is not null.

Hi,

The .so file might contain null bytes like a string end char is \0 aka null.

You are using a python environment to run your block, you should select the C++ environment since it's a C++ block.

I just checked and it was missing from the list of available environments. It now has been fixed.

Best regards

I am now seeing this error with the environment:

RuntimeError: Environment `Cxx backend (2.0.0)' is not available on docker host `Docker host' - available environments are Python (2.1.0), Deep Learning (1.0.0), Allies (0.0.1), C++ (2.0.0)

Cxx backend (2.0.0) is the only environment available for the C++ algorithm.

Sorry, there was a configuration issue.

It has been fixed.

Is there any way to see additional debugging information? My algorithm runs for a few thousand images in the dataset until I see an error "[sys] Missing data on the following output(s): histogram". 

This is the code I am using to generate the output:

Hi,

Following up here, are there any additional errors logged in this case? 

Thanks!

Hi,

I found:

 Writing output\n[sys] Missing data on the following output(s): histogram\n"

Thanks,

I've seen this error and I was wondering if there was any more specific information available. The algorithm works for a number of inputs but abruptly stops with this error, so it would be helpful to have an idea of what exactly is going on here.

AFAIK, it means that the execution of your algorithm has ended properly and somehow there was not enough data written on the output.

What type of algorithm is that (sequential, autonomous) ?

Are you writing only once to the output ?

Best regards

It is a sequential algorithm and I'm writing only once to the output. I've included a screenshot of the entire algorithm below:
