How to check which conda environment is running on Nvidia GPU-CodePudding

I want to know who is using which GPUs.

For example.

After nvidia-smi

 ----------------------------------------------------------------------------- 
| Processes:                                                                  |
|  GPU   GI   CI        PID   Type   Process name                  GPU Memory |
|        ID   ID                                                   Usage      |
|=============================================================================|
|    0   N/A  N/A      6260      C   python                           1203MiB |
|    0   N/A  N/A     19842      C   python                           7735MiB |
|    1   N/A  N/A       594      C   python                           1703MiB |
|    1   N/A  N/A      6260      C   python                           1371MiB |
|    1   N/A  N/A     19842      C   python                           5343MiB |

Here I want know which conda environments are using for each PIDs.
(Because for our team, we use different conda envs)

What I want is

PID : 6260 = env1  
PID : 19842 = env2   
...

Thank you.

Conda environment activation is only a state of a shell session. Short of recovering that state from the parent process, the next best thing might be inspecting the process path. For example, I can check some like:

$ top

$ readlink -f /proc/25/exe
/opt/conda/bin/python3.9

$ readlink -f /proc/116/exe
/opt/conda/envs/foo/bin/python3.10

which are the base and foo environments, respectively.
