USAGE:
npy-write [OPTIONS]
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
OPTIONS:
-d, --dtype <type> data type, one of: u32, i32, u64, i64, f32, f64 (default: f32)
-o, --output <FILE> output file name (default: data.npy)
-s, --separator <S> character used to separate fields (default: space)
For example in
cat lots-of-big-integers.txt | npy-write -o nicematrix.npy -d u64 -s ' '
lots-of-big-integers.txt might look like
0 53 49
0 2721 4
0 1679 5
0 1974 8
3 12207 1
1 2698 3
1 5561 2
3 217 2
0 12532 2
0 1456 2
and the output nicematrix.npy would then be
In [2]: np.load('nicematrix.npy')
Out[2]:
array([[ 0, 53, 49],
