2 years ago Hi, I'm joining in and asking as well for clarification of the tutorial.
About 2.: dai is probably short for depthai, so I just wrote in my code:
import depthai as dai
and of course replaced 'depthai' with dai in two lines where it's still called that way.
But there are more:
- the following code line is probably just an example:
detection_nn.setBlobPath("/path/to/mobilenet-ssd.blob")
But there is no info how to get the blob. I took a look at full code at github (https://github.com/luxonis/depthai-tutorials/blob/master/1-hello-world/hello_world.py) and there you have instead:
detection_nn.setBlobPath(str(blobconverter.from_zoo(name='mobilenet-ssd', shaves=6)))
- But as I further inspected the whole .py at github, I've noticed that there the pipeline methods are called differently at several lines, e.g.:
detection_nn = pipeline.createMobileNetDetectionNetwork()instead of this in the tutorial:detection_nn = pipeline.create(dai.node.NeuralNetwork)
Then I checked the tutorial history on github and saw that after there was a commit " update tutorials to latest API (#294) " on 21 June, there was a an another commit "Merge branch 'develop' into gen2_scripting" on 24 June that changed the way the pipeline methods were called, as already mentioned above.
Is the older version of the tutorial from 21 June really using an older API? Because I constantly get errors with the current version of the tutorial:
Traceback (most recent call last):
File "c:\Users\mpv98\AIKIT\depthai-tutorials-practice\1-hello-world\hello_world.py", line 27, in <module>
detection_nn.setConfidenceThreshold(0.5)
AttributeError: 'depthai.node.NeuralNetwork' object has no attribute 'setConfidenceThreshold'Then I have commented out the line and got the next error:
Traceback (most recent call last):
File "c:\Users\mpv98\AIKIT\depthai-tutorials-practice\1-hello-world\hello_world.py", line 62, in <module>
detections = in_nn.detections
AttributeError: 'depthai.NNData' object has no attribute 'detections'

Hi, I just started my journey playing with the OAK-D camera and I found some "glitches" in the hello world tutorial. I thought about proposing a Pull Request with corrections, but I do not know enough about the project yet to make proper corrections. Therefore, I just wanted to mention it here so that somebody else hopefully can take the feedback and improve the documentation page:
Define a pipelinethere are references todai. But that object or alias is not defined before. I actually noticed that in the code repository with the examples,daiis not used anymore.
