Do you have both files and directories inside your path? os.listdir will list both files and directories, so when you try to open a directory with np.load it will give that error. You can filter only files to avoid the error:

data_paths = [os.path.join(in_dir, f) for f in os.listdir(in_dir)]
data_paths = [i for i in data_paths if os.path.isfile(i)]

Or all together in a single line:

data_paths = [i for i in (os.path.join(in_dir, f) for f in os.listdir(in_dir)) if os.path.isfile(i)]
