How to get outdated files?

[ErnestTBass]

Below is a listing of a requirements.txt file for some software python code that I am trying to run.

absl-py==0.7.0
astor==0.7.1
editdistance==0.5.2
gast==0.2.2
grpcio==1.18.0
h5py==2.9.0
Keras-Applications==1.0.7
Keras-Preprocessing==1.0.8
Markdown==3.0.1
numpy==1.16.1
opencv-python==4.0.0.21
protobuf==3.6.1
six==1.12.0
tensorboard==1.12.2
tensorflow==1.12.0
termcolor==1.1.0

when I run this file:

pip install -r requirements.txt

I get nothing like the version numbers of the applications that I should install.

It seems to me that these apps are quite old and are unobtainable.

Is it possible to get them and if I can, how do I get them?

Respectfully,

May be not the correct answer but I suppose many of these libraries have a publicly available repository. If you clone the repositories, you should be able to check out past versions.

Thanks I will give it a try.I always use the command

pip install

or

conda install

In this however, I used the command

pip install -requirements.txt.

Thanks again.

Respectfully,
