Can you give us more information on your error. There should be more debugging info also, what OS are you using?

What is your pandas version ? To know that, in a Python console in QGIS, you can type the following line by line:

import pandas
print(pandas.__version__)

I solved problem to set up old pandas version now run qgis :)
