After Fusion 360 background update, I need to reinstall numpy . . . . . . .

[jackie.lin.945]

for my windows directory
C:\Users\myName\AppData\Local\Autodesk\webdeploy\production\

there are some subdirectory.

ex : one is 65899d0f0113f775e86f30ece2eeaf89fc855cb7

After Fusion 360 Background auto update, it seems Fusion will add a new subdirectory.

There is only one dir has many system files.
After update, I need to reinstall numpy module to run my script correctly.
Sometime I did no noticed that Fusion has silently update.
I run my script, Fusion not showing error, but no result that is I expect.
I check every where and then I reinstall numpy, it became normal.
How do I know Fusion is updated and I need to reinstall numpy???????
Thank you.

I gather you install numpy in your fusion installation by adding it to the path in the .env. As you've noticed, this solution causes problems when fusion is updated as the version hash number changes. If you want to have non standard library imports, i'll advise using a folder directly in your add-in/script directory and adding that path to sys.path with sys.path.insert.

Hello,

I quickly wrote an add-in that displays a dialog at startup if Fusion 360 has been updated: New version info

But you should also consider the advice given by @tykapl.breuil

Hi Fellows,

I have adopted a slightly different strategy. It is as follows:

• Install an independent version of Python
• and the same version as in F360
• load it with all python modules you like
• create environmental variable referring to the ...\Python??\Lib\site-packages
• in F360 script, using this variable attach this path 
• sys.path.append( packagesPath) 
• use imports as normal 

In my case it works, ... but I will not give warranty 😏.
