bestfit | Draw the best fit line over a set of points | iOS library

Relatively new to Dash, and this is a problem that has been vexing me for months now. I am making a multi-page app that shows some basic data trends using cards, and graphs embedded within cardbody. 30% of the time, the app works well without any errors and the other 70% it throws either one of the following:

1. ImportError: cannot import name 'ValidatorCache' from partially initialized module 'plotly.validator_cache' (most likely due to a circular import) OR
2. ImportError: cannot import name 'Layout' from partially initialized module 'plotly.graph_objects' (most likely due to a circular import)

Both these appear quite randomly and I usually refresh the app to make them go away. But obviously I am doing something wrong. I have a set of dropdowns that trigger callbacks on graphs. I have been wracking my head about this. Any help/leads would be appreciated. The only pattern I see in the errors is they seem to emerge when the plotly express graphs are being called in the callbacks.

What am I doing wrong? I have searched all over online for help but nothing yet.

Sharing with some relevant snippets of code (this may be too long and many parts not important to the question, but to give you a general idea of what I have been working towards)

I'm trying to get the output that is supposed to show but the blockSize is the same as memorySize (which is decreasing but I need my blockSize to stay as its initial one) Plus if there's any improvement of best fit that you can suggest, do tell!

I am a beginner trying to use cufflinks to produce a scatter chart. The optional argument to include best fit line is bestfit=True. The code to produce this chart looks like this:

When i try and run my code, i get this error:
error: method getTest1 in class Assess cannot be applied to given types;
double fit = Assess.getTest1(sol1[0],sol1[1]); ^
required: double[]
found: double,double
reason: actual and formal argument lists differ in length
I cant find a fix. Any help would be much appriciated. Thanks

I'm playing around with data from SDSS (Sloan Digital Sky Survey) to plot and analyze spectra from stars. To do this, I downloaded a .csv file from their website from which I would extract each line and its data and then plot this data. The data came in the format Wavelength, Flux, BestFit, SkyFlux, but I'm only really interested in the wavelength and best fit. I just wanted to mention that so my code would make more sense. I've tried to run every 10 and 100 datapoints but I haven't been able to solve me. Any help would be appreciated. There is a graph of the wanted result on the SDSS website, I've pasted it just below:

Here is the graph that my code produced (Obviously VERY wrong):

Here is the code:

I have a code with for loop like below and it ends with some if statements;

I heve some problems with making UI in Unity3d. I have a dropdown element with 5 DDN items. This is original structure of DDN.

But on wide screen DDN items not responsive(2736x1824).

This is on FreeAcpect screen.

I want to make an elements responsive, but unity don't make it itself. I try to set BestFit checkbox of Text element but no results.

I have a Matlab reference routine that I am trying to convert to numpy/scipy. I have encountered a curve fitting problem that does I cannot solve in Python. So here is a simple example which demonstrates the problem. The data is completely synthetic and not part of the problem.

Let's say I'm trying to fit a straight-line model of noisy data -

I have been doing a course on data science and machine learning and in one of the lesson, it asked me to download and use plotly and cufflinks. I downloaded and installed them successfully, I have imported them successfully as well. But while trying to use them using iplot, it's giving me an error. Below I have attached screenshots of the error so I want to know how to solve this error and use plotly and cufflinks without any issue.

The code that I wrote:
