keras==1.2.2 is conflicts with other libraries

[osok]

The current requirements.txt is not valid.

INFO: pip is looking at multiple versions of keras to determine which version is compatible with other requirements. This could take a while.
ERROR: Cannot install -r requirements.txt (line 6) and keras==1.2.2 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested keras==1.2.2
    tensorflow 2.10.1 depends on keras<2.11 and >=2.10.0
    The user requested keras==1.2.2
    tensorflow 2.10.0 depends on keras<2.11 and >=2.10.0

    The user requested keras==1.2.2
    tensorflow 2.8.0 depends on keras<2.9 and >=2.8.0rc0

EDIT Update I did upgrade my local requirements.txt so that keras==2.11.0 and this works. J+However I have a new problem below.

I get that these are likely problems outside of this project, but they are in the requirements.txt and when they don't work the environment is not able to support the project.

Fixed : I was only ever trying python 3.9, 3.10 and 3.11, since there are security issues with 3.8 and there is no longer any support. Well going back to python 3.8 this worked.
