QUESTION
I use the standard formula to rotate a solid (filled) rectangle/object with pivot point. The image is a on/off byte array.
...ANSWER
Answered 2021-Feb-22 at 20:40To avoid holes in image after rotation you have to loop through destination pixels (instead of source pixels). This (using nearest neighbor) works well for images that have:

I am trying to minimize a function with scipy.optimize
with three input variables, two of which are bounded and one has to be chosen from a set of values. To ensure that the third variable is chosen from a predefined set of values, I introduced the following constraint:

QUESTION
I am trying to run a distributive application with PyTorch distributive trainer. I thought I would first try the example they have, found here. I set up two AWS EC2 instances and configured them according to the description in the link, but when I try to run the code I get two different errors: in the first terminal window for node0 I get the error message: RuntimeError: Address already in use
Under the other three windows I get the same error message:
RuntimeError: NCCL error in: /pytorch/torch/lib/c10d/ProcessGroupNCCL.cpp:272, unhandled system error
I followed the code in the link, and terminated the instances an redid but it didn't help/
This is using python 3.6 with the nightly build Cuda 9.0. I tried changing the MASTER_ADDR to the ip for node0 on both nodes, as well as using the same MASTER_PORT (which is an available, unused port). However I still get the same error message.
After running this, my goal is to the adjust this StyleGan implementation so that I can train it across multiple GPUs in two different nodes.
...ANSWER
Answered 2019-Aug-29 at 06:34So after a lot of failed attempts I found out what the problem is. Note that this solution applies to using ASW deep learning instances.
After creating two instances I had to adjust the security group. Add two rules: The first rule should be ALL_TCP, and set the source to the Private IPs of the leader. The second rule should be the same (ALL_TCP), but with the source as the Private IPs of the slave node.
Previously, I had the setting security rule set as: Type SSH, which only had a single available port (22). For some reason I was not able to use this port to allow the nodes to communicate. After changing these settings the code worked fine. I was also able to run this with the above mentioned settings.
QUESTION
I know there is tons of similar issues that are similar to mine and i've gotten a few mixed answers but i am not sure which one will work with mine but my foreach is only returning one item from my json api I am getting.
JSON
...ANSWER
Answered 2017-Dec-18 at 19:10It's because return $data;
is inside foreach()
, which terminates the loop immediately after first iteration and only first data is returned.
Put it outside of foreach()
loop and you will good to go.
