and thus getting a map
which you can access by key.

QUESTION
I am trying to find a good example to understand the time and the space complexity (in Big O notation) when recursively map a random tree.
I found examples for a binary search tree, but I am not sure if this case will apply to my case.
Let suppose we have a tree of nodes. Each of these nodes can have a random number of child nodes as well.
ParentNode[ChildNode1.1[ChildNode2.1,ChildNode2.2], ChildNode1.2[ChildNode2.3]]
My task consist into copy the ParentNode into a new CopyNode with all the children. For that, my functions is:
...ANSWER
Answered 2020-Nov-27 at 22:22node.copy()
is called exactly once per each source node. Time complexity is indeed O(N)
(N
being the number of nodes in a source tree).
Space complexity is proportional to the depth of the source tree. Worst case is again O(N)
.
Testing for a special case of node.getChildren().empty()
is not necessary.

I have an t2.2xlarge AWS EC2 instance that i need to change it's type to t3.2xlarge. But when i try to start it i get an

When i run the check script everything is fine

Answered 2020-Nov-24 at 20:53I tried to launch a t3.2xlarge
in us-east-1e
and got the following error:
Your requested instance type (t3.2xlarge) is not supported in your requested Availability Zone (us-east-1e). Please retry your request by not specifying an Availability Zone or choosing us-east-1a, us-east-1b, us-east-1c, us-east-1d, us-east-1f.
AWS probably doesn't have t3.2xlarge
instances available in this AZ.
QUESTION
I'm trying to run Pytorch on a laptop that I have. It's an older model but it does have an Nvidia graphics card. I realize it is probably not going to be sufficient for real machine learning but I am trying to do it so I can learn the process of getting CUDA installed.
I have followed the steps on the installation guide for Ubuntu 18.04 (my specific distribution is Xubuntu).
My graphics card is a GeForce 845M, verified by lspci | grep nvidia

ANSWER
Answered 2020-Oct-31 at 21:26PyTorch doesn't use the system's CUDA library. When you install PyTorch using the precompiled binaries using either pip
or conda
it is shipped with a copy of the specified version of the CUDA library which is installed locally. In fact, you don't even need to install CUDA on your system to use PyTorch with CUDA support.
There are two scenarios which could have caused your issue.
You installed the CPU only version of PyTorch. In this case PyTorch wasn't compiled with CUDA support so it didn't support CUDA.
You installed the CUDA 10.2 version of PyTorch. In this case the problem is that your graphics card currently uses the 418.87 drivers, which only support up to CUDA 10.1. The two potential fixes in this case would be to either install updated drivers (version >= 440.33 according to Table 2) or to install a version of PyTorch compiled against CUDA 10.1.
To determine the appropriate command to use when installing PyTorch you can use the handy widget in the "Quick start locally" section at pytorch.org. Just select the appropriate operating system, package manager, and CUDA version then run the recommended command.
In your case one solution was to use
