Description
I realized that some datasets have issues with their md5 hash. Check for example:
wget https://www.openml.org/data/v1/download/61/iris.arff && md5sum iris.arff
wget https://www.openml.org/api/v1/data/61 && cat 61 | grep md5_checksum
showing that either the md5 checksum for the dataset, or the dataset is broken.
Overall, 19 datasets have this problem in total: 61, 250, 252, 299, 310, 311, 316, 537, 543, 1029, 1547, 1548, 1549, 1551, 1552, 1553, 1554, 1555, 4546

Research direction
Start with the two wget/md5sum checks shown in the issue, comparing each of the 19 listed dataset IDs with its API md5_checksum. Determine whether each mismatch is caused by the stored checksum or the downloaded dataset, then verify that all affected datasets and checksum values agree.
