NengoDL installation issue

Hi,

I have an issue installing nengo-dl. I can install the latest versions from tensorflow, keras, nengo in anaconda prompt with pip, but when it comes to nengo-dl it only let me install the 2.2.0 version.
The error message is the following:

ERROR: Could not find a version that satisfies the requirement nengo-dl==3.4.1 (from versions: 0.2.0, 0.3.0, 0.3.1, 0.4.0, 0.5.0, 0.5.1, 0.5.2, 0.6.0, 0.6.1, 0.6.2, 1.0.0, 1.1.0, 1.2.0, 1.2.1, 2.0.0, 2.1.0, 2.1.1, 2.2.0, 2.2.1, 2.2.2, 3.0.0, 3.1.0, 3.2.0, 3.3.0, 3.4.0, 3.4.1)
ERROR: No matching distribution found for nengo-dl==3.4.1

Please let me know if you have any idea why this could be.

Hi!

Could you post your Python version, and any packages you have installed in your environment (do pip freeze). It’ll be easier to debug this issue with that information. Thanks! :slight_smile:

Hi!
Thank you for replying! I created the environment in anaconda with python 3.7.10. I installed numpy 1.19.5, scipy 1.7.0, matplotlib 3.4.2, tensorflow 2.5.0,tensorflow-gpu 2.5.0, keras 2.4.3, nengo 3.1.0, nengo-gui 0.4.8, then I tried to instal nengo-dl and it only let’s me install the 2.2.0.

I link the rest of the error message, I do not understand why I do not have any issue installing the rest of the packages or the older version of nengo-dl only the newer versions throw this anomaly.

Thank you!

I am unable to replicate the errors you are experiencing, so it must be an issue with the environment you have created. I would advise trying the install again in a new environment.
To test, the following command install Nengo, NengoDL, NengoGUI, and TensorFlow all in a single environment:

conda create -n test python=3.7.10
conda install tensorflow==2.5.0
pip install nengo nengo-gui nengo-dl matplotlib scipy

When I do this on my system, I get the following packages installed (this is the output of conda list):

Thank you for your suggestion, unfortunately this order of install results the same way for me. I tried to reinstall anaconda a dozen time and with several environments, always the same issue. Thank you for your time.

Just out of curiosity, if you did pip install nengo-dl in an empty environment, what version does it install?

Hi, I am afraid I am getting the same result it only allows to install nengo -dl2.2.0.

Hmm. This seems very odd. Can you provide the conda list of your base environment? I would hazard a guess that there are some packages in your base environment that is causing this issue.

Sure, thank you for looking into this.

So… your base environment might be the one causing the issue. Also, I realized after you posted the reply that my commands didn’t include the conda activate command that may have installed additional packages into your base environment.

In any case, let’s try to fix it. The first thing you should do is to make a backup of your C:\Users\****\Anaconda3\envs folder. Either move that entire folder to another location, or make a copy of that folder to another location (e.g., C:\Users\****\Backup)

Next, uninstall Anaconda, and be sure to delete the C:\Users\****\Anaconda3 folder. Then, reinstall anaconda, and try to reinstall all of the packages using the commands below:

conda create -n snntest python=3.7.10
conda activate snntest
conda install tensorflow==2.5.0
pip install nengo nengo-gui nengo-dl matplotlib scipy

If this still fails to work, try the following pip command instead:

pip install nengo-dl --no-cache-dir

Hi,
Thank you, I did try both the same error messages pop up all the time.

Can you please post the full error message? Include everything from the when the pip install command was issued.

I am sorry I haven’t got back to you sooner I have some issues with my PC. When everything is running again I shall post it. Thank you.
