Facing error in running sdk_sample DCGMReader.py

[premalathak12]

/test1/DCGM/sdk_samples$ cmake . CMake Error at CMakeLists.txt:18 (install): install FILES given no DESTINATION!

-- Configuring incomplete, errors occurred!

Tried exporting DESTINATION variable with a empty directory. Still getting same error. Can this be run inside container only ?

Please let me know, how to build and run DCGMReader.py.

@premalathak12,

DCGM build system is designed to run inside the dcgm build container (the dcgmbuild directory provides a way to make it). Our Cmake does not support in-tree build, and sdk_samples are part of the whole project build - it requires the environment defined in the top-level CMakeLists.txt

@nikkon-dev I have not builded as i was getting some errors but installed the datacentre-gpu-manager. In the /usr/local/bindings/ able to run dcgm_example.py. Copied the dcgm_readerexampley.py from sdk_samples and tried to run it. I got a error :

    self.LogDebug("fieldGroupId: " + findByNameId  + "\n")
TypeError: can only concatenate str (not "c_void_p") to strFile "/usr/local/dcgm/bindings/python3/DcgmReader.py", line 402, in GetFieldMetadata
    self.LogDebug("fieldGroupId: " + findByNameId  + "\n")
TypeError: can only concatenate str (not "c_void_p") to str 

So added it as str(findByNameId). That error got resolved.

Now when i run DCGMreaderexample.py again, i am getting Using custom fields through the dictionary interface... For gpu 0 field mem_copy_utilization=0 For gpu 0 field gpu_utilization=0 For gpu 0 field power_usage=14.762

Processing in field order by overriding the CustomerDataHandler() method

Is this a valid approach ? Please suggest me a way to resolve this error, So i can see the output of DCGMReaderExample ?
