[FLASH-USERS] How to extract and plot HDF5 data using yt

[ZhaoXu]

Hi Jiale,

It seems the working directory is not properly set.

yt.load('sedov_forced_hdf5_plt_cnt_0000') -> 
yt.load('filedir/sedov_forced_hdf5_plt_cnt_0000')

filedir is your data location.

and I suggest running python with Jupyter notebook or spyder/pycharm, 
such IDE

Hope this help

Best

Xu
