Tái hiện các lỗi trong distarray/globalapi/tests/test_distarray.py, đặc biệt là test_mean_dtype, test_var_dtype và test_std_dtype, cũng như trong distarray/globalapi/tests/test_distributed_io.py đối với test_save_load_with_filenames. Theo dõi các lệnh gọi qua distarray/globalapi/distarray.py và distarray/globalapi/context.py, sau đó xác minh rằng các bài kiểm thử này chạy đạt với NumPy 1.10 và việc tải dựa trên tên tệp hoạt động.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
