Error in running .cti file

[Pawan Ojha]

Hi Cantera group,

Cantera is throwing an error whenever I am running a .cti file. However, it runs smoothly with XML or YAML files. The error is attached. 

Any help would be highly appreciated!! 

CanteraError:

Hi,

The error is listed at the bottom of the log, you need to install NumPy in the same environment as Cantera. NumPy is required to use Cantera in Python. However, the CTI format (and XML) is deprecated and will be removed after Cantera 2.6, so I would suggest you stick with YAML.

Best,

Bryan
