I need to read output from a child process as it's produced -- perhaps not on every write, but well before the process completes. I've tried solutions from the Python3 docs and SO questions here and here, but I still get nothing until the child terminates.

The application is for monitoring training of a deep learning model. I need to grab the test output (about 250 bytes for each iteration, at roughly 1-minute intervals) and watch for statistical failures.

• I cannot change the training engine; for instance, I cannot insert stdout.flush() in the child process code.
• I can reasonably wait for a dozen lines of output to accumulate; I was hopeful of a buffer-fill solving my problem.

Code: variations are commented out.

I was going through the python docs to improve my core python and I was reading about errors and exceptions

In the doc it says

If a finally clause includes a return statement, the finally clause’s return statement will execute before, and instead of, the return statement in a try clause.

It also provides this example below:

I was self-studying CSAPP and got a strange result when I ran into a strange issue during the run of a assertion test.

I'm not sure what to start this question with, so let me get the code first (file name visible in comments):

I'm new to Tensorflow and image processing, I use a code that converts bitmap to an Inputarray for predict object from Tensorflow Lite library and Firebase MLKit custom model API. I'm trying to normalize channels values to the range[0.0,1.0]. Comments are written show that this function normalizes channels values to a range of [-1.0,1.0] and can be normalized to [0.0,1.0] but doesn't explain how to do that. How can I do that?

Update

The reason for that question is to get correct values from tflite model on an image from ibug dataset: I have a Tensorflow Lite model and I want to predict eye region landmarks values, I tried to predict eye region points with an image as input and with an array of values ( x and y coordinates ) as output.

I got a python script that gets predictions from an image using Tensorflow lite model.

I'm trying to execute a script that extracts face from the ibug dataset.

This is my personal GH Pages site.

I have this set in my /_config.yml:

I need to develop a list that contains all possible combinations in order of the elements in n lists. Basically I'm trying to find all the possible paths, which I will need later for another part of my program.

I've already made some simple code for two lists, but the problem is that I don't know how many inputs will the user give, so I have to guess. For the moment I've defined a function that outputs all possible combinations (1 way only, because they're paths). I've been also testing other alternatives like itertools (which I think may hold the answer to my problem), or using numpy arrays (the problem with this is that my array isn't homogeneous).

The input list may look something like this (3 dimensions):

(Note: I know that a personal access token will work, but external reasons require me to do this via an SSH Deploy Key. Both the source repo and the target repo are private.)

I need to use CircleCI to push every commit from the source repo to the target repo. Assume the repos are named source and target. I am configuring CircleCI to run my custom push script but it's saying that the key is read-only.

What I've done:

• Created a new key pair with ssh-keygen on my PC and compress the private key.
• Uploaded the public key id_rsa.pub to the target repo as a Deploy Key, with "allow push access with this key" ticked.
• Put the compressed private key in the repository Environment Variables on CircleCI
• Wrote this script:

Summary: I want to receive packets from a single interface, but setsockopt(sock, SOL_SOCKET, SO_BINDTODEVICE, iface, 1 + strlen(iface)) doesn't play well with recvfrom and shows all packets on all interfaces. tcpdump works well, however.

I have a strong feeling that there's something wrong with the receiver program, but I haven't been able to figure it out.

I'm working with a Netronome Agilio CX SmartNIC. The two ports on the NIC are connected together with one cable, and the port on the motherboard are connected to the wall (so I can SSH into it). The board-loaded NIC is eth0 in the OS, while the SmartNIC presents two interfaces as enp1s0np0 and enp1s0np1.

Because the two interfaces on the SmartNIC has no associated IP addresses, I have to send broadcast to one port so it arrives at the other port. For now, I send to enp1s0np0 and expect it from enp1s0np1.

I have also deployed a XDP offload program that modifies part of the packet so I can know whether the packet arrives at enp1s0np1. The program changes the string at position 28~35 to another string (of the form !......!).

The problem I am having is, I wrote a receiver program myself, and it receives two packets for every packet I send - the first is the original, while the second is the XDP-modified packet. However, tcpdump only receives the modified packet (expected behavior).

I am unsure why my program is getting it twice - I don't think it should be able to see the unmodified packet.

This is the packet sender program. It reads 32 double-precision floating point numbers and packs them into a 256-byte block, and prepends the block with 16 bytes of "magic numbers".
