@Jie-Yuan is this executed from a notebook? If so, make sure you understand the notebook example (https://github.com/maxpumperla/hyperas/blob/master/examples/simple_notebook.ipynb) and examine some of the existing issues on this topic. If not, simply make sure that the folder /0_c/ on your machine, from which you seem to be calling hyperas, has proper access rights.
