There are more than 60k images of hand gestures in the training set.

From the above link you will be able to download a zip file named 'asl_alphabets.zip’. After you extract this zip file, you will get four files:

train - contains all the images that are to be used for training your model.
Training_set.csv - this csv file has contains the labels for the training images
test - contains 26000+ images. For these images you are required to make predictions
Testing_set.csv - this is the order of the predictions for each image that is to be submitted on the platform. Make sure the predictions you submit are with their image’s filename in the same order as given in this file.
sample_submission.csv- this is the sample submission file for the data sprint
