Installation fails due to conflicting pandas version

[NeolithEra]

Issue description

Hi, users are unable to run erpnext due to dependency conflict with pandas package.

As shown in the following full dependency graph of erpnext, erpnext requires pandas (the latest version)，while frappe requires pandas==0.14.1.

According to pip’s “first found wins” installation strategy, pandas==0.25.0 is the actually installed version. However, pandas==0.25.0 does not satisfy pandas==0.14.1.

Suggested solutions

1. Fix your direct dependency to be pandas==0.14.1. I have checked this revision will not affect your downstream projects now.
2. Ask your upstream project frappe to loose the version range to pandas>=0.14.1.

Which solution do you prefer, 1 or 2?

@rohitwaghchaure Please let me know your choice. I can submit a PR to solve this issue.
