Hi Momen Kadry,
We noticed your feedback that the above answer was not helpful. Thank you for taking time to share feedback.
The Azure for Students account comes with certain limitations, including a maximum of 3 virtual CPUs, which prevents the creation of GPU-enabled VMs. To access GPU resources, you must upgrade to a Pay-As-You-Go subscription, though this may not be a viable option for all students. GPU Optimized VM's are the N series VM's. By default, the quota on the subscription for this type of VM's are set to 0.
As you have said you have requested quota increased and it is approved, make sure the quota increase was applied to the same region where you are trying to create the VM.
- Go to Azure Portal → Subscription → Usage + quotas
- Filter by Region and check the quota for N-series VMs.
If the VM sizes are not available in your current region, try creating the VM in another region that supports N-series VMs.
Request a quota submission here for the VM available region.
In case you want to move to pay-as-you-go offering, please check the details here.
You can try spot vm's but availability is highly variable and depends on unused capacity in your chosen region. Some N-series (GPU) VMs are available as Spot instances, but they may be evicted frequently.
We recommend submitting this feature request directly via the Azure Feedback Portal (https://feedback.azure.com). The product team will get to know your need for resources for student accounts.
