It might be broken for me, as I said the program works without the offline mode but gets interrupted and shows the results from above with offline mode. But there might be another issue in between of course - any idea how to debug?
The environment variable is good to know, I will try with that as well and report back.

For local testing, we have added a

ScantChimpanzee51 there is already an environment variable for that, you can just set CLEARML_OFFLINE_MODE 🙂

By the way, if we don’t wrap other calls in

is_offline()

we get errors like “DateTime object is not serializable”, but that’s a secondary issue.

I think this was fixed, can you verify with the latest RC 1.7.3rc0 ? If this still happens can you share the code

However, this results in the process getting interrupted, the outputs show:

Are you saying offlinemode is broken ?

How could I reproduce this issue ?

I think I missed this one, what exactly is the issue ?

BTW, this one seems to work ....
` from time import sleep
from clearml import Task

Task.set_offline(True)
task = Task.init(project_name="debug", task_name="offline test")

print("starting")

for i in range(300):
print(f"{i}")
sleep(1)

print("done") `

I meant maybe me activating offline mode, somehow changes something else in the runtime and that in turn leads to the interruption. Let me try to build a minimal reproducible version 🙂

Thanks ScantChimpanzee51 !
Let me see what I can find, should be easy enough to fix now 🙂

Hi AgitatedDove14 , so it took some time but I’ve finally managed to reproduce. The issue seems to be related to writing images via Tensorboard:
` from torch.utils.tensorboard import SummaryWriter
import torch
from clearml import Task, Logger

if name == "main":
task = Task.init(project_name="ClearML-Debug", task_name="[Mac] TB Logger, offline")
tb_logger = SummaryWriter(log_dir="tb_logger/demo/")
image_tensor = torch.rand(256, 256, 3)
for iter in range(10):
tb_logger.add_image(f"images/image123/img", image_tensor, iter, dataformats="HWC")

task.flush(wait_for_uploads=True) `Again the errors show up as

I’m also happy to open an issue on GitHub with the details if you like 🙂
By the way no rush about this - we will turn off TB logging in the meantime.
Thanks for all the help!

Let me try to build a minimal reproducible version

Thank you!

Happy to and thanks!

So AgitatedDove14 if we use the CLEARML_OFFLINE_MODE environment variable instead the program runs through again.
The only thing is that now we get errors of the form

Any idea where that could come from? Could we turn off the local logging as well - in these kinds of runs we don’t need it?

It is supposed to create it automatically... I tested with other examples (clearml version 1.7.3rc1) everything seems to work
What am I missing? how do we recreate the issue ? can you verify it is still not working with the latest RC?

By the way, if we don’t wrap other calls in is_offline() we get errors like “DateTime object is not serializable”, but that’s a secondary issue.
