Or well, because it's not geared for tests, I'm just encountering weird shit. Just calling task.close() takes a long time
This seems to be fine for now, if any future lookups finds this thread, btwwith mock.patch('clearml.datasets.dataset.Dataset.create'): ...
UnevenDolphin73 are you saying offline does not work?
stream.write(msg + self.terminator) ValueError: I/O operation on closed file.This is internal python error, how come there is no stream?
Yes exactly that AgitatedDove14
Testing our logic maps correctly, etc for everything related to ClearML
I think it basically runs in offline mode and populates all the relevant fields (Task attributes) in some json (or some other config file). I think you could read this file and compare to something that is expected thus having an ability to run something offline and then verify it's contents.
I guess the thing that's missing from offline execution is being able to load an offline task without uploading it to the backend.
Or is that functionality provided by setting offline mode and then importing an offline task?
Last but not least - can I cancel the offline zip creation if I'm not interested in it 🤔
EDIT: I see not, guess one has to patch ZipFile ...
😢 any chance you have a toy pytest that replicates it ?
I dunno :man-shrugging: but Task.init is clearly incompatible with pytest and friends
I'll try it out, but I would not like to rewrite that code myself maintain it, that's my point 😅
Or are you suggesting I Task.import_offline_session ?
Seems like Task.create is the correct use-case then, since again this is about testing flows using e.g. pytest, so the task is not the current process.
I've at least seen references in dataset.py 's code that seem to apply to offline mode (e.g. in Dataset.create there is if output_uri and not Task._offline_mode: , so someone did consider datasets in offline mode)
I guess the thing that's missing from offline execution is being able to load an offline task without uploading it to the backend.
UnevenDolphin73 you mean like as to get the Task object from it?
(This might be doable, the main issue would be the metrics / logs loading)
What would be the use case for the testing ?
Last but not least - can I cancel the offline zip creation if I'm not interested in it
you can override with OS environment, would that work?
Or well, because it's not geared for tests, I'm just encountering weird shit. Just calling
task.close()
takes a long time
It actually zips the entire offline folder so you can later upload it. Maybe we can disable that part?!
` # generate the script section
script = (
"from clearml import Dataset\n\n"
"ds = Dataset.create(dataset_project='{dataset_project}', dataset_name='{dataset_name}', dataset_version='{dataset_version}')\n".format(
dataset_project=dataset_project, dataset_name=dataset_name, dataset_version=dataset_version
)
)
task.data.script.diff = script
E AttributeError: 'NoneType' object has no attribute 'diff' `Well this is something you should probably not do, there is no "data" object in offline it never accessed the backend
This is with:Task.set_offline_mode(True) task = Task.init(..., auto_connect_streams=False)
Or if it wasn't clear, that chunk of code is from clearml's dataset.py
no, at least not yet, someone definitely needs to do that though haha
Currently all the unit tests are internal (the hardest part is providing server they can run against and verify the results, hence the challange)
For example, if ClearML would offer a
TestSession
that is local and does not communicate to any backend
Offline mode? it stores everything into a folder, then zips it, you can access the target folder or the zip file and verify all the data/states
Seems like
Task.create
is the correct use-case then, since again this is about testing flows using e.g. pytest,
Make sense
This seems to be fine for now, ...
Sounds good! thanks UnevenDolphin73
I'm running tests with pytest , it consumes/owns the stream
If you create an initial code base maybe we can merge it?
Should not be complicated, it's basically here
https://github.com/allegroai/clearml/blob/1eee271f01a141e41542296ef4649eeead2e7284/clearml/task.py#L2763
wdyt?
Yeah I managed to work around those former two, mostly by using Task.create instead of Task.init . It's actually the whole bunch of daemons running in the background that takes a long time, not the zipping.
Regarding the second - I'm not doing anything per se. I'm running in offline mode and I'm trying to create a dataset, and this is the error I get...
There is a data object it, but there is no script object attached to it (presumably again because of pytest?)
It does, but I don't want to guess the json structure (what if ClearML changes it or the folder structure it uses for offline execution?). If I do this, I'm planning a test that's reliant on ClearML implementation of offline mode, which is tangent to the unit test
I'm working on the config object references 😉
Another example - trying to validate dataset interactions ends with
` else:
self._created_task = True
dataset_project, parent_project = self._build_hidden_project_name(dataset_project, dataset_name)
task = Task.create(
project_name=dataset_project, task_name=dataset_name, task_type=Task.TaskTypes.data_processing)
if bool(Session.check_min_api_server_version(Dataset.__min_api_version)):
get_or_create_project(task.session, project_name=parent_project, system_tags=[self.__hidden_tag])
get_or_create_project(
task.session,
project_name=dataset_project,
project_id=task.project,
system_tags=[self.__hidden_tag, self.__tag],
)
# set default output_uri
task.output_uri = True
task.set_system_tags((task.get_system_tags() or []) + [self.__tag])
if dataset_tags:
task.set_tags((task.get_tags() or []) + list(dataset_tags))
task.mark_started()
# generate the script section
script = (
"from clearml import Dataset\n\n"
"ds = Dataset.create(dataset_project='{dataset_project}', dataset_name='{dataset_name}', dataset_version='{dataset_version}')\n".format(
dataset_project=dataset_project, dataset_name=dataset_name, dataset_version=dataset_version
)
)
task.data.script.diff = script
E AttributeError: 'NoneType' object has no attribute 'diff' `
But that should not mean you cannot write to them, no?!
Coming back to this; ClearML prints a lot of error messages in local tests, supposedly because the output streams are not directly available:

mostly by using

UnevenDolphin73 , now I'm confused , Task.create is Not meant to be used as a replacement for Task.init, this is so you can manually create an Additional Task (not the current process Task). How are you using it ?
Regarding the second - I'm not doing anything per se. I'm running in offline mode and I'm trying to create a dataset, and this is the error I get...
I think the main thing we need to test is offline Dataset creation... I do not think this was actually supported. What is the use case here? or should it be a pass-through ?
Or if it wasn't clear, that chunk of code is from clearml's dataset.py
Oh! that makes sense 🙂
Note that it would succeed if e.g. run with pytest -s
