need TensorFlow 2.1.6

[suedorward]

Hey @jbusecke, how can I upgrade TensorFlow to 2.1.6? I need it to run keras_nlp on Keras 3 (it only supports Tensorflow under Keras 3).

This is for a ML class project due on 12/22 so I would love a solution this week. It is for an approach that Prof. Gentine specifically suggested that I try.

Thanks
Sue

Hi @suedorward , sorry for the delay here.

I am working on this right now. What would be helpful here is a code snippet that I can execute and confirm that it works.

If urgent please ping me on the LEAP slack.

Overall this is quite a complex dependency problem here.
I followed the instruction to install keras_nlp on keras 3 and they did not work!

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
tensorflow 2.15.0.post1 requires keras<2.16,>=2.15.0, but you have keras 3.0.1 which is incompatible.

I managed to update keras to 3 with the following chain of commands in the terminal

pip install --upgrade tensorflow
pip install --upgrade keras-nlp
pip install --upgrade keras>=3 --no-deps

Note that you will have to do this procedure every time you start up a server

But I don't exactly know how to confirm that this installation works properly, so please test it on your end, and let me know.

They mention that all of this should go away after tensorflow 2.16, but that won't help in your case.

I tried this previously - the problem is that
pip install --upgrade tensorflow
installs 2.1.5

keras_nlp requires Tensorflow 2.1.6.

Here's my sample code:

try:
system('pip show tensorflow')
import keras_nlp
except:
system('pip install --upgrade tensorflow')
system('pip install --upgrade keras-nlp')
system('pip install --upgrade keras>=3 --no-deps')
print("Installed tensorflow, keras-nlp, and keras3.\nRun all cells after auto kernel restart.\nNo need to modify any code.")
exit(0)

After the install, the output from system('pip show tensorflow') is:

Ah, I just saw some documentation that says Keras 3 will work with Tensorflow 2.1.5. I can't find where it said 2.1.6. I will see if I can get this working. Thanks

Found it. When I tried to upgrade previously, pip gave me the message:
tensorflow 2.15.0 requires keras<2.16,>=2.15.0, but you have keras 3.0.0 which is incompatible.

But maybe 2.15.0.post1 will work.

[suedorward]

Keras says Tensorflow 2.1.5.0 should work (despite the pip message above)
https://keras.io/getting_started/ says:

To use Keras 3:

tensorflow==2.15.0 & keras==3.0.0
tensorflow==2.16.0 & keras==3.0.0
