Hi:
Are you doing Neural Networks within the Advanced Analytics Professional level of the Data Science Academy? Or, are you working in the AI&ML level of the Data Science Academy?
If you are using THIS Neural Network Modeling class:
![Cynthia_sas_0-1596208808563.png Cynthia_sas_0-1596208808563.png](https://communities.sas.com/t5/image/serverpage/image-id/47836iDDE8EBFF09321329/image-size/medium?v=v2&px=400)
Then the Virtual Lab is NOT numbered 2. There is only one Virtual Lab for the Advanced Analytics Professional set of 4 classes.
If you are working in the AI&ML level of the Academy, then Virtual Lab 2 is ONLY for the Deep Learning class:

If you started from a FRESH image, there is nothing saved from previous sessions. If you are working in Lesson 4 on Tuning Neural Networks, then there are not any practices at the end of that section, as shown below:
![Cynthia_sas_2-1596209371628.png Cynthia_sas_2-1596209371628.png](https://communities.sas.com/t5/image/serverpage/image-id/47838iDDF6A4040E5DC8B0/image-size/medium?v=v2&px=400)
Are you doing the demo in Lesson 4? The class instructor has been building demos throughout the other lessons. If you are working from a FRESH image, none of that demo work would have been done before Lesson 4.
At the top of the video, you can see a note that says "This demonstration proceeds from the previous one. Libraries and in-memory data used here are created and loaded in DLUS03D02."

And if you print the demo steps, you see this:
![Cynthia_sas_4-1596209758966.png Cynthia_sas_4-1596209758966.png](https://communities.sas.com/t5/image/serverpage/image-id/47840i1C07F506AE757D5A/image-size/medium?v=v2&px=400)
So if you are working in the Deep Learning class you can ONLY use Virtual Lab 2. The Virtual Lab 1 is used for the other 4 classes in the AI&ML Level.
I hope this helps explain that Virtual Lab 2 is the correct lab for the Deep Learning class.
