@zhl5317 Can you go to Network

[hlomzik]

Hi! This error shows that image was not loaded for some reason. Could you please show the top of console output? You can hide all urls except protocols, I'm just interested in errors)

@zhl5317
Why do you have doubled "completions" seсtions?

completions:
{
  "completions": [
...

[zhl5317]

@makseq

no, Just one example

actually my completions is:

[makseq]

@hlomzik Can you check this issue about canvas: https://github.com/niklasvh/html2canvas/issues/1859
It seems really something strange in it...

[makseq]

@zhl5317 do you have this trouble in the each task?

[zhl5317]

@makseq

no， other image tagging task are all ok， only “object detection“ have this trouble

[makseq]

@zhl5317 I explored your completion more detailed and found that there is "ellipselabels" inside, but you are talking about bboxes. I think you broke the integrity somewhere between the labeling config and task completions, e.g. you changed the labeling config manually.

[zhl5317]

@makseq

thank you for your attention

actually, i think my data is ok, because the data is created by LS tagging, not created by by myself. the following pic is my test data

{ "completions": [ { "created_at": 1598929260, "id": 1001, "lead_time": 4.093, "result": [ { "from_name": "label", "id": "f2I9aRX-3x", "image_rotation": 0, "original_height": 403, "original_width": 600, "parent_id": null, "source": "$image", "to_name": "image", "type": "rectanglelabels", "value": { "height": 56.96517412935324, "rectanglelabels": [ "Airplane" ], "rotation": 0, "width": 22.666666666666668, "x": 39.333333333333336, "y": 31.8407960199005 } } ] } ], "data": { "image": "https://app.heartex.ai/static/samples/sample.jpg" }, "id": 1 }

you can try "Bbox object detection" in your side to check whether has the issue

[makseq]

I checked your completion on my side. Everything is ok...
Do you use google chrome? Or some custom version of it?

[zhl5317]

@makseq

yes, im using chrome, Is there a compatibility issue on Chrome?

[makseq]

Maybe. I'm trying to do some checks.
Can you try another browser? And please show your label config.

[zhl5317]

@makseq
anyway, thank you for your quick reply, i will track my configrations in more detail, and i will try on other another browser

mysql label config is official website example
<View> <Image name="image" value="$image"/> <RectangleLabels name="label" toName="image"> <Label value="Airplane" background="green"/> <Label value="Car" background="blue"/> </RectangleLabels> </View>

I will give you feedback on any discovery， one more thanks

[zhl5317]

@makseq

i try on other browser (ie Edge) is ok,

but on chrome sometimes is ok, sometime will occurs " Failed to execute 'drawImage' on 'CanvasRenderingContext2D': The image argument is a canvas element with a width or height of 0", its very strange

[makseq]

@zhl5317 Do you still have this issue? Can you try release 0.7.5rc3? (it's in pypi: pip install label-studio==0.7.4rc3)

[makseq]

I faced this issue. The problem could be in the too small area where LSF is placed. Try to pre-define it at least with width=500px.

[makseq]

@zhl5317 Does it help you?

[korotaS]

I faced this issue. The problem could be in the too small area where LSF is placed. Try to pre-define it at least with width=500px.

Hi @makseq ! I also faced this issue. Where can i pre-define the LSF area width?

[makseq]

@korotaS Hi, I hope we fixed it since 0.7.5.post0 release. Check this release, please.
