[14.0] account_loan module can not be installed

[tv-openbig]

If i open a runbot in order to test the functionality of the account_loan module it can't be installed.

Module

account_loan

Describe the bug

Module should normally alreday installed if i understand runboat functionality correct.

To Reproduce

1. Open a runboat instance
2. Extend your rights by "Full accounting" group assignation to your user (admin)
3. Detect that you can't find any menu related to "loan"
4. Go to Apps menu and try to install account_loan by hand.
5. Here it stucks in status "To be installed"
   

Expected behavior
In order to test the module should be installed already or it should complete the manual installation.

On a local system installation was successful after installation of the following python packages:
numpy
numpy-financial
I have installed them by pip3 on my Ubuntu 20.04

I am not sure if i should close the issue

@OCA/accounting-maintainers runboat for v14 have effectively been failling in the last month+ (no module is installed after account_loan), could you address this issue?

Thanks!

I am reviewing it and I think I found the origin of the issue...

same issue with numpy version, impossible to install the requirements with

Python 3.9.2 (default, Feb 28 2021, 17:03:44) 
[GCC 10.2.1 20210110] on linux

changing the numpy version helps to solve the issue.
