pipenv - Pipfile.lock is not being generated due to the 'Could not find a version that matches keras-nightly~=2.5.0.dev' error

As the title clearly describes the issue I've been experiencing, no Pipfile.lock is being generated as I get the following error when I execute the recommended command pipenv lock --clear:

ERROR: ERROR: Could not find a version that matches keras-nightly~=2.5.0.dev

There are incompatible versions in the resolved dependencies.

So, how can I overcome this situation? I'm basically developing a deep neural network using Keras. I simply installed the following dependencies without explicitly declaring versions:

tensorflow = "*"
nltk = "*"
pandas = "*"
tweepy = "*"
textblob = "*"
seaborn = "*"
matplotlib = "*"
wordcloud = "*"
stop-words = "*"
vadersentiment = "*"
scikit-learn = "*"
keras = "*"

adding those line to Pipfile fixed my issue.

[pipenv]
allow_prereleases = true

It seems that tensorflow does not work on python 3.9 as it has a dependency on the nightly.

If you are using python 3.9, your option is to go to tensorflow 2.6.0rc1,

Pipenv wants you to use the --pre flag in this situation. I think the simplest way to install it would be like this:

pipenv install tensorflow --python=3.8 --pre

By Changing the python_version in pipenv file resolved my issue.

I had it 3.9 before.

Pipfile:

python_version = "3.8"

I had the same problem. Apparently, tensorflow arises a sub-dependency resolution error with Pipfile when resolving keras. It searches for a version that matches keras-nightly~=2.5.0.dev. Looking at pypi, this version does not exist.

Whatsoever, installing a version 2.4.X works, e. g. pipenv install tensorflow~=2.4.1.

By looking at the pypi site for keras-nightly library, I could see that there are no versions named 2.5.0.dev. Check which package is generating the error and try downgrading that package.
