Description

according to our documentation we can write with a specific block size:

write(X, "test/generated.data", format="binary", rows_in_block =16000, cols_in_block = 16000)

The writing goes through without a problem, but afterwards it is not possible to read the file.

also when writing you can set the cols_in_block to anything, and it does not effect the output.
