I cannot seem to get a working install of Nengo on Windows 10.
First, I uninstalled all Python libraries, and then uninstalled Python itself, and then removed any Python reference from the environmental variables. So, I had a clean system to start with.
Next, following the detailed installation instructions, I installed Anaconda, using the install file:
So far, so good.
Then I opened the Anaconda command prompt and entered:
pip install nengo nengo-gui
Then everything went bad. I got these messages:
Collecting nengo Using cached nengo-3.1.0-py3-none-any.whl (523 kB) Collecting nengo-gui Using cached nengo_gui-0.4.7-py3-none-any.whl (843 kB) Requirement already satisfied: numpy>=1.13 in c:\users\mark\anaconda3\lib\site-packages (from nengo) (1.19.2) Installing collected packages: nengo, nengo-gui ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts. We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default. nengo-gui 0.4.7 requires nengo<=3.0.0,>=2.6.0, but you'll have nengo 3.1.0 which is incompatible. Successfully installed nengo-3.1.0 nengo-gui-0.4.7
I then attempted to run Nengo anyway, and got pages and pages of errors. Any ideas? I’m relatively unexperienced with Python, so be gentle!
