Hi

I just installed ttcrpy using pip and when I try to run the simple examples notebook, I get an error while importing tmesh.

I hope someone can help me with this.

Hi; Try to install a more recent version of numpy (1.20.0 for example). To do that, reinstall numpy by successively running these 2 lines in a terminal: pip uninstall numpy pip install numpy On Apr 15, 2021, at 7:39 AM, Tushar03 ***@***.******@***.***>> wrote: Attention : ce courriel provient d'un expéditeur externe.

@tgautam03 Did upgrading numpy solve the problem? If not, what is the error message?

Thanks

Sorry, I didn't receive the email regarding the fix.

I reinstalled everything and now it works well. However I'm not able to figure out how to use the library. The tutorials aren't elaborative enough.

I'm trying to do refraction tomography on 2D models and need ray tracing as well as travel times for my inversion code.
