F1 CAR DETECTION-8cb6a7

Update in Evaluator

8 days ago

Hi all!

We have now updated the evaluator to take the right format from the submission file (x_min, y_min, x_max, y_max) and have completed re-evaluations.

For those who are seeing lower score as compared to previous score, please update the submission file from the format (x_min, x_max, y_min, y_max ) to (x_min, y_min, x_max, y_max).

Here the code to convert the submission into the right format

# Importing Libraries
import pandas as pd
from ast import literal_eval

# Reading the submission file
submission = pd.read_csv("submission.csv")


# Going through each row
for index, row in submission.iterrows():

    # Convert the bounding boxes from string to python list
    bboxes = literal_eval(row["bboxes"])[0]

    # Convert the bounding boxes to the right format
    new_bboxes = [[bboxes[0], bboxes[2], bboxes[1], bboxes[3], bboxes[4]]]

    # Making changes to the row
    submission["bboxes"][index] = new_bboxes

# Saving the changes into a new submission file
submission.to_csv("new_submisson.csv", index=False)

Sorry for the inconvenience caused.

Regards,
Shubhamai

Downloading datasets

13 days ago

I just tried downloading dataset using cli and it seems ok for me. Have your tried downloading dataset using baseline and got the same issue ? Can you try out this code and see if it works as intended -

!pip install aicrowd-cli
API_KEY = “YourAPIKEY”
!aicrowd login --api-key $API_KEY
!aicrowd dataset download --challenge f1-car-detection -j 3

Round 5 Dataset

About 1 month ago

Why there is mini dataset ( less than 5 GB ) not provided for getting started ? I am pretty sure many of us are having problems with just downloading & unzipping datasets in for ex. Google Colab.

Hi @Ram_98

The Mars planed in only rotated on Z axis, can you share the samples which seems to be rotated on multiple axis ? I will check again on my side.

About the new datasets for WinPrediction

3 months ago

Hi,

I thoroughly checked if there still were any bugs, but couldn’t find any. These are games from real players, maybe that is why some rare samples may contain these inconsistencies.

Nope, i mean there is no label representing castling or en-passant move.

Seems like in the dataset we only have instances of promoted pawn.

Update on Win Prediction puzzle | New evaluator

3 months ago

Yep, we figured out the mistake that was there in the dataset & have updated it!

In this challenge, you have to predict the side that is going to win based on a snapshot of the board a few steps before checkmate. So you should be good to go!

The turn column is in sample_submission.csv & you will soon be able to download test.csv too!

CHESS TRANSCRIPTION

Castling notation

3 months ago

Hi,

Yep, So, the ground truth of 695.mp4 from the test dataset was h3h4 d7h3 f2f3 e8c8 h4g5 h6f8 d1d2 in which case our dataset didn’t account for the rook move, it only accounted for the king move which was e8c8.

We were python-chess to generate the dataset. And it seems like python-chess only accounts for the king move in castling.

About white passed pawn

3 months ago

Hi victorkras2008

We are still investigating the issue but here’s the bare minimum code to generate pawn promotion moves from chess-python library ( which we used to generated the dataset ) .

# Importing Libraries
import chess
import random


# Creating a chess board
board=chess.Board()

while True:

  # If no legal move, continue
  if list(board.legal_moves) == []:
    print("continue")
    continue


  # Make random move
  move = random.choice(list(board.legal_moves))
  
  # If there was any pawn promotion, print the move & board
  if len(move.uci()) > 4:
    print(move.uci())
    print(board)
    print('--'*20)


  # Make the move in board
  board.push_uci(move.uci())
  
  # If Game Ends, Reset chess board!
  if board.is_game_over() == True:
    board=chess.Board()
    continue   

And here’s the sample output -

The issue is python-chess doesn’t consider which side ( black/white ) had the pawn promotion.
