However, nothing is saved along this path

The /root/clearml.conf file no longer contains anything.

@<1523701205467926528:profile|AgitatedDove14> thanks for your reply! Do I also need to change the path for docker_pip_cache ?

None

I store my data in s3 and clearml tracks this data. I want to migrate this data from one ClearML instance to another, that is, transfer it to another s3 and have a new ClearML instance track it

How to override /root/.cache/pip path?

okey, I see, thank you!

Hi @<1523701205467926528:profile|AgitatedDove14>
I started an experiment with gpus=2 and node=2 and I have the following logs

@<1523701435869433856:profile|SmugDolphin23> hi! it works! thanks!

Hi @<1523701435869433856:profile|SmugDolphin23> ! I set NODE_RANK in the environment and now

• if gpus=2, node=2, task.launch_multi_node(node) : three tasks are created, and two of which are completed, but one is failed. In this case, are created (gpus*nodes-1) of tasks, some of which crashes with an error, or they all fall with an error. the behavior is inconsistent.

Hi @<1523701087100473344:profile|SuccessfulKoala55> No, I am using self-hosted ClearML enterprise server

@<1523701435869433856:profile|SmugDolphin23> gloo doesn't work for me either

but torch work with nccl and task.launch_multi_node

problems arise specifically with pytorch-lightning

Can you help me?

for example, global rank from failed task in first scenario

@<1523701435869433856:profile|SmugDolphin23> Everything worked after setting the variables: --env NCCL_IB_DISABLE=1 --env NCCL_SOCKET_IFNAME=ens192 --env NCCL_P2P_DISABLE=1. But previously, these variables were not required for a successful launch. When I run ddp training with two nodes , everything works for me now. But as soon as I increase their number ( nodes > 2 ), I get the following error.

Traceback (most recent call last):

The errors that occur in the second case are presented in this screenshots.

Hi @<1523701205467926528:profile|AgitatedDove14>
I define a pipeline through functions. I have a lot of parameters, about 40. It is inconvenient to overwrite them all from the window that is on the screen.

@<1523701435869433856:profile|SmugDolphin23> This error occurs when a secondary task is created with launch_multi_node. And this error disappears when I add the reuse_last_task_id=False flag when initializing the task. But now I have a new problem. I can't request more than 2 nodes. The training logs freezes after several iterations of first epoch with three workers. And if i request four workers i get this error:

DEBUG Epoch 0:   8%|▊         | 200/2484 [04:43<53:55,  0.71it/s, v_num=...

If I understand correctly, the cache for pip is stored at /root/.cache/pip. How can I change it? The agent.docker_internal_mounts.pip_cache variable in the config also does not change anything.

Hi @<1523701087100473344:profile|SuccessfulKoala55> where can I get examples of REST API requests for creating reports?

in the clearml section in values.yaml:

clearml:

  clearmlConfig: |-
   agent.docker_pip_cache="/mnt/pip_cache"
