it fixes the issue This error indicates that you have an old version of Stripe's Python library installed in your production environment. The create method for Subscriptions was added on version 1.33.0 released on 2016-05-04. You'll want at least that version in production.

Opening csv file in Python: builtins. AttributeError AttributeError: '_io.BytesIO' object has no attribute 'file'

should help you out io.TextIOWrapper takes a io.BytesIO object all right.
You're (almost) passing it, except that you're adding a .file (why??), which is not a field of the io.BytesIO class (request.files['portfolios'] is a io.BytesIO object already)
code :
csvfile = TextIOWrapper(request.files['portfolios'], encoding=request.encoding)

AttributeError: 'GMM' object has no attribute 'covariances_' || AttributeError: 'module' object has no attribute 'Gaussi

around this issue In the new versions from 0.18 onwards, GMM has been deprecated and GaussianMixture is used in place of that as can be seen in the documentation here.
Now for your first error, it seems that you have an older version of scikit-learn which dont have the GaussianMixture class yet. And for your second error, older GMM did not have the attribute covariances_. Use covars_ attribute instead. See the older documentation here:-
code :
Covariance parameters for each mixture component. 
The shape depends on covariance_type:

This might help you When trying to use the .config() method to change the font size of the 'button1' attribute of the 'studentmainmenuscreen' object I got this error: Error , You're changing the type of object in line:
code :
self.button1 = Button(self.canvas, text=b1t, command=b1c, font=('Arial', 30), relief='flat').place(x=b1x,y=b1y)
self.button1 = Button(params)
self.button2 = Button(params)

Attribute Error at the Grader: AttributeError: 'LinearRegression' object has no attribute 'predict_proba'

By : ESilva

this will help The linear regression module indeed does not have a predict_proba attribute (check the docs) for a very simple reason: probability estimations are only for classification models, and not for regression (i.e. numeric prediction) ones, such as linear regression.
Since it is not clear from your post if you are trying to do regression or classification:
