Where can i upload the pickle file on the webserver as when i upload the. pkl file in main directory it shows no file name or directory clf. Pkl

[akashb12]

I am trying to deploy a machine learning model on a web server of digital ocean which predict the probability of disease based on its symptoms. For this i am using ubuntu 18.04 console and flask. My working directory is

var/www/na/na

All the files are uploaded in above directory. Content of directory will be posted below. Everything works fine i successfully hosted my website. This is my flask code

from flask import Flask,request,render_template,redirect,url_for,session,logging,flash
from flask_sqlalchemy import SQLAlchemy
import pymysql
pymysql.install_as_MySQLdb()

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://root:@localhost/naksh_main'
db = SQLAlchemy(app)
# creating content in database
class Naksh_main_tb(db.Model):
    sno = db.Column(db.Integer, primary_key=True)
    datetime = db.Column(db.String(12), unique=False)
    email = db.Column(db.String(20), unique=True, nullable=False)
    password = db.Column(db.String(20), unique=True, nullable=False)

@app.route('/')
def index():
    return render_template('index.html')

@app.route('/register',methods=['GET','POST'])
def register():
    if(request.method=='POST'):
        "fetch entry from database"
        # u name is just a variable which is storing name content of form
        uname=request.form.get('uname')
        passw=request.form.get('passw')

        existing_entry=Naksh_main_tb.query.filter_by(email=uname).first()
        if existing_entry:
            flash('Email already exist')
            return redirect(url_for("register"))
        # to add entry
        # email from database will store uname variable and password from database will store passw variable
        new_entry=Naksh_main_tb(email=uname,password=passw)
        db.session.add(new_entry)
        db.session.commit()
        return redirect(url_for("login"))
    return render_template("register.html")

@app.route('/login',methods=['GET','POST'])
def login():
    if(request.method=='POST'):
        "fetch entry from database"
        louname=request.form.get('uname')
        lopassw=request.form.get('passw')
        login=Naksh_main_tb.query.filter_by(email=louname,password=lopassw).first()
        if login is not None:
            # flash('pleas check')
            return render_template('nakshoverview.html')

        # else:
        #     return redirect(url_for("login"))
    return render_template("login.html")

@app.route('/',methods=["GET","POST"])
def hello_world():
    if request.method == "POST":
        print(request.form)
        # mydict will access the form using name
        mydict=request.form
        fever=int(mydict['fever'])
        pain=int(mydict['pain'])
        runnynose=int(mydict['runnynose'])
        diffbreath=int(mydict['diffbreath'])

# now here we can use names like fever pain inplace of values
        probability=mp.predict_proba([[fever,pain,age,runnynose,diffbreath]])
        # model.predictproba is used to predict probability

        prob=probability[0][1]
        # to select the probabilty using index 1
        print(prob)
        #this will return inf value and display it in show.html
        # return redirect(url_for('index'))
        return render_template('show.html',inf=round(prob*100))
    return render_template('index.html')

if __name__== "__init__":
    db.create_all()
    app.run(debug=True)

Above code works fine But when i try to deploy my machine learning model which is saved using a pickle file it throws an error. Problem occurs when i try to open clf. pkl file

from flask import Flask,request,render_template,redirect,url_for,session,logging,flash
from flask_sqlalchemy import SQLAlchemy
import pymysql
pymysql.install_as_MySQLdb()

app = Flask(__name__)
import pickle

# open a file, where you stored the pickled data
file = open('model.pkl', 'rb')

# dump load model information to that file
mp = pickle.load(file)

# close the file
file.close()

app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://root:@localhost/naksh_main'
db = SQLAlchemy(app)
# creating content in database
class Naksh_main_tb(db.Model):
    sno = db.Column(db.Integer, primary_key=True)
    datetime = db.Column(db.String(12), unique=False)
    email = db.Column(db.String(20), unique=True, nullable=False)
    password = db.Column(db.String(20), unique=True, nullable=False)

        passw=request.form.get('passw')

        # email from database will store uname variable and password from database will store passw variable
        new_entry=Naksh_main_tb(email=uname,password=passw)
        db.session.add(new_entry)

My wsgi file is saved as na. wsgi in directory

var/www/na

Code for wsgi is

#!/usr/bin/python3
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/na/")

from na import app as application
application.secret_key = 'Add-secret'

Machine learning code

import pandas as pd
import numpy as np
import pickle
from sklearn.model_selection import train_test_split
from sklearn.linear_model import LogisticRegression

df=pd.read_csv('covidnew.csv')

train_set,test_set=train_test_split(df,test_size=0.2,random_state=42)
# this will print length of test set and train set
print("test data is",len(test_set))
print("train data is",len(train_set))

# for training:seperating features and labels
x_train_feature=train_set.drop(["prob"],axis=1)
y_train_label=train_set["prob"].copy()

# to convert to array
x_train_feature.to_numpy()
y_train_label.to_numpy()

# for testing:seperating features and labels
x_test_feature=test_set.drop(["prob"],axis=1)
y_test_label=test_set["prob"].copy()

x_test_feature.to_numpy()
y_test_label.to_numpy()

# logistic regression
clf=LogisticRegression()
# model=DecisionTreeRegressor()
# model=RandomForestRegressor()
# fit function takes label and features
clf.fit(x_train_feature,y_train_label)

# open a file, where you ant to store the data
file = open('model.pkl', 'wb')

# dump model information to that file
pickle.dump(clf, file)
file.close()

When i run this code using python3 na.py it creates an model. pkl file but i am not able to load this file in my init.py

Hi @akashb12,

This issue does not seem to be related with the XBee Python Library. Are you sure you created it in the correct GitHub project?

Regards.
