KeyError: 'inference' when applying solution weight to my data #232

willsbit · 2020-09-30T18:08:51Z

I'm trying to predict on new data using the model weights that were made available on neptune.ai
After struggling a bit with some other errors, I managed to get to the python main.py predict_on_dir \ command.

This is the command I'm running

!python open-solution-mapping-challenge/main.py predict-on-dir \
--pipeline_name scoring_model \
--chunk_size 1000 \
--dir_path inference_directory \
--prediction_path resultados/predictions.json

I tried predict_on_dir but it said that command doesn't exist in main.py
now I'm stuck with this error:

I'm using google colab btw
Suggestions?

Hi @willsbit,

I think you should get it to work with predict_on_dir -> perhaps reading about using Click (package) on colab could help.
Other than that I don't know what may be wrong.

Also, I have to say, I am not sure when will I be able to get to this issue. Sorry

willsbit · 2020-10-01T22:05:37Z

@jakubczakon Using only the first level model (unet) instead of scoring_model seems to solve the inference error, but now I'm getting some numpy exceptions

I noticed the squeeze_inputs function is in src/utils.py, but I don't know how to fix it

jakubczakon · 2020-10-02T06:12:47Z

The squeeze_inputs function problem, as I remember, was usually because of the incorrect pytoroch version.
Are you using the version specified in the requirements.txt?

willsbit · 2020-10-02T17:21:56Z

torch==0.3.1
torchvision==0.2.0 and
numpy==1.16.4 seem to fix it

and I got a new RunTimeError

I noticed that the data/checkpoints folder hadn't been created automatically... perhaps it's because I didn't train the model myself? I was thinking it could maybe be related to the issue

willsbit · 2020-10-02T18:34:00Z

forget what I said, I reuploaded unet and scoring_model to the transform folder and now it outputs the predictions

I tried using the predictions.json as ground truth, but after removing the {} (i was getting list type not supported), this is what i get:

I'd suggest to just use predict_on_dir to get those predictions.

It seems that there is an issue with indexing which was discussed (with fixes) here.

I hope this helps

willsbit · 2020-10-05T13:20:10Z

It works, yay! Thank you for all your help @jakubczakon
Does it only work with 300x300 or can it be any image size? Also, do you know if .tif files are supported?

pscheich · 2020-10-21T21:52:59Z

Hey @willsbit

I had the same error as you:
pipeline = PIPELINES[pipeline_name]['inference'](SOLUTION_CONFIG) KeyError: 'inference'

and my solution is not using
--pipeline_name scoring_model
I've used
--pipeline_name unet_tta_scoring_model.

As described in REPRODUCE_RESULTS.md -> "Predict on new data"

willsbit · 2020-10-21T22:15:48Z

@pscheich didn't work for me :/
I got

File "/content/drive/My Drive/open-solution-mapping-challenge/src/postprocessing.py", line 358, in get_contour
    _, contours, hierarchy = cv2.findContours(mask.astype(np.uint8), cv2.RETR_TREE, cv2.CHAIN_APPROX_NONE)

jakubczakon · 2020-11-06T11:57:07Z

Hi @vishwa15

unet_tta_scoring_model is the pipeline name that:

uses the unet model (you downloaded)
uses TTA (test time augmentation)
uses scoring_model to pick the best thresholds per image

So in short you don't need to download it, you already have all the pieces.

@jakubczakon I got it. Usually, saved model will be a single file. Here, we need two files. Thank you for clarifying.
