cannot import cxrayutilities #75

Closed Jon2515 closed 5 years ago

Jon2515 commented 5 years ago

I have a mac OS, I am using anaconda and spyder IDE. I am trying to run sample code. I run import xrayutilities as xu. Several things import then I get an error, it says:

anaconda/pkgs/xrayutilities/io/cbf.py", line 25, in from .. import config, cxrayutilities

ImportError: cannot import name 'cxrayutilities'

So, does anyone know why this is happening, and how to get around it?

Thanks for the help!

could you describe how you installed xrayutilities?

this error usually indicates that the installation process was not completed successfully. Especially the compiling of the included c-library! Please refer to the README and/or documentation for information regarding the installation.

From the Mac Terminal. Initially, I did pip install xrayutilities. It gave errors and said it wasn't installed when I tried to import xrayutilities into a program. I then did pip install --global-option="--without-openmp" xrayutilities this time it installed and said it was successful. When I import it to a program and run it I get the message described initially.

could you please provide the following to help me better understand what could have gone wrong...

remove xrayutilities for example by pip uninstall xrayutilities and post/upload the output of pip -v install --force --global-option="--without-openmp" xrayutilities

It has been resolved. Thank you for your assistance.

My issue was: I had downloaded the package, then moved it into the directory for python packages, then I did pip install. I didn't realize when one does pip install it automatically goes to the internet and downloads it and installs it.
