Steps to reproduce

  1. Create fresh conda venv w/ Python 3.8.1 (last known working version of VXRD);
  2. Followed README.md instructions to install requirements.txt;
  3. Ran Flask w/ flask run

Error

 * Serving Flask app "vxrd.py"
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
Usage: flask run [OPTIONS]

Error: While importing "vxrd", an ImportError was raised:

@qzhu2017, I'm having trouble resolving this issue with relative import statements. Maybe you have some insight or can help.

By the way, it still works in my older conda virtual environment which explicitly had pyxtal-xrd installed from PyPI, back when it was still available:

(vxrd) stanley@PAVILION-13:~/github/sabaronett/XRD/flask$ pip list
Package         Version
--------------- -------------------
...
pyxtal-xrd      0.0.2

@qzhu2017, never mind; I forgot to run setup.py in root first—it's working now.

I'll update README.md per #31 and close this issue.

As the (V)XRD project has merged into PyXtal, resolved in https://github.com/qzhu2017/PyXtal/commit/43fc4a02cd284c41ed45613bbd232bf6c61f00b2. See also #31 and 9258e4845dd8cc3d5326eb41604309d57f453d27 for add'l info.

Closing issue.
