Plankton | Open source simulator for maritime robotics researchers

I am trying to show the values such as "Broader","Narrower" on the arrows on a graph but i dont know how to do it. I have read the previous posts such as how to draw directed graphs using networkx in python? and read the documentation (https://networkx.org/documentation/latest/_downloads/networkx_reference.pdf) of NetworkX but i cant make it happen.

My code is mentioned below;

I have a problem about implementing recommendation system by using Euclidean Distance.

What I want to do is to list some close games with respect to search criteria by game title and genre.

After calling function, it throws an error shown below. How can I fix it?

Here is the error

I am working on an assignment where I am creating a webpage about sharks and I need to know how I can center my images. I have already tried the align attribute in my code and my images are still not centered. I would like the images to be in the center of the screen.

Here is my image code:

Here are the images on the actual webpage:

Here is my code (if needed)

I just built my first AWS Apache Server and uploaded my website from my school project. The site works in Dreamweaver. However on my Apache server only some of the images appear. They all have the same path and are contained in the same folder /var/www/html/images. Some appear as intended, others are a broken link. Any ideas why it's not working? To get css to load I had to move my css folder. With the images some work fine while others do not. They are roughly the same size files. This is the code for one of the non working images:

I have some oceanographic data (time, depth, plankton counts, salinity, temperature, etc.) from the deployment of oceanographic equipment. The deployment consisted of multiple profiles of the water column. I subsetted all downcasts in the data (when the equipment was descending), so that when I plot depth over time, the data look like this: depth over time.

What code or function can I use in R to automatically identify, isolate, and extract the data from each individual downcast into its own object (without having to specifically identify the times of each downcast)? For the data in the plot, it would essentially generate 6 objects. Ideally, the code could easily be applied to other deployments with 1-7 downcasts each.

I've been looking at identifying data break points or structural changes, but nothing has been fruitful. Thank you!!

I have an reactjs app that uses a django backend to deal with authentication.

Here are the pertinent parts of my App.tsx Typescript code for my react app.

I define this in my Apps.jsx file of a React project:

I need to understand what factors can explain the implementation of a directive. My design includes Biogeographic Region with 2 Levels, a nested variable within Biogeographic Region - Marine Sub-Unit - with 3 levels within each Biogeographic Region level and Criteria (16 levels) and Groups (11 levels). Each Marine Sub-unit includes counts concerning Criteria and Group. All my factors are categorical.

An example of a data frame, sum, is:

Biog_Reg Marine.Sub.Unit Criteria Group Count

Celtic Seas FR_Celtic Seas 1.1 Benthic habitats 1

Celtic Seas FR_Celtic Seas 1.1 Fish 15

Celtic Seas FR_Celtic Seas 1.1 Marine mammals 6

Celtic Seas FR_Celtic Seas 1.1 Marine turtles 6

Celtic Seas FR_Celtic Seas 1.1 Pelagic habitats 0

Celtic Seas FR_Celtic Seas 1.1 Plankton 0

Celtic Seas FR_Celtic Seas 1.1 Rock & Biogenic Reef 0

Celtic Seas FR_Celtic Seas 1.1 Seabirds 14

Celtic Seas FR_Celtic Seas 1.1 Sedimentary habitat 1

Celtic Seas FR_Celtic Seas 1.2 Fish 0

Since I am addressing nested count data and I want to access all proper interactions, I am trying to use GLMM to perform the analysis. I have tested several models but the most complete includes the following design:

Model3 <- glmer (Count ~ Biog_Reg + Criteria + Group + Biog_Reg: Criteria+ Biog_Reg:Group + (1|Marine.Sub.Unit/Biog_Reg), family = poisson (), data = sum)

(I understand that going instead for the following model would be easier but it simply wouldn't run: Model3 <- glmer (Count ~ Biog_Reg * Criteria * Group + (1|Marine.Sub.Unit/Biog_Reg), family = poisson (), data = sum) )

However, the model takes a very long time to resolve and when it does, provides the following errors:

"Correlation matrix not shown by default, as p = 54 > 12. Use print(x, correlation=TRUE) or vcov(x) if you need it convergence code: 0 unable to evaluate scaled gradient Model failed to converge: degenerate Hessian with 2 negative eigenvalues failure to converge in 10000 evaluations Warning messages: 1: In vcov.merMod(object, use.hessian = use.hessian) : variance-covariance matrix computed from finite-difference Hessian is not positive definite or contains NA values: falling back to var-cov estimated from RX"

I am relatively new in GLM in general, so I have several questions:

1. Do I have the type of model and model syntaxe correct? My variable is naturally nested, i.e. each Marine Sub-unit only belong to one of the two Biogeogrpahic Region, so should a simpler anova solve this?
2. In spite of the errors, the model provides results for each level of each factor individually. If the model is correct, how can I obtain the results for the factor?
3. Should I nest Criteria and Group within Marine Sub-Unit, evend though they are not ramdom? If so, how is the sintaxe for it?
4. Should I consider Hurdle models instead?

I have already read a huge amount of information but considering: "Schielzeth, H. and Nakagawa, S. (2013), Nested by design: model fitting and interpretation in a mixed model era." I should go for mixed models and GLMM with Poisson distribution. This should handle count data. I have encountered many resembling questions but none specifically answered my doubts.

Please help!!!

I'm doing a project that trains a model that can classify plankton images. However, when I am doing my code and run it, it says that my image is in a folder that it cannot identify. First, I thought it have some with problem with the file name. I changed all jpg to png. But nothing changed. Every image on that folder works fine.
I am not using PIL, so I am still trying to figure out what is my problem, but nothing changed.The folder exists, and the image works normally.
Here is my code:
