I want to try out Streamlit Sharing (https://www.streamlit.io/sharing). This is my locally working code:
streamlit_app.py
import pandas as pd
import streamlit as st
from PIL import Image
from sklearn.ensemble import RandomForestClassifier
from sklearn.model_selection import train_test_split
# Model
df = pd.read_csv("IRIS.csv")
X = df.drop(columns=["species"])
y = df["species"]
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.33, random_state=42)
rf = RandomForestClassifier()
rf.fit(X_train, y_train)
# Streamlit
st.header("Iris Classification")
image = Image.open("iris.jpg")
st.image(image, use_column_width=True, output_format="jpg")
st.write("Please insert values, to get Iris class prediction")
SepalLengthCm = st.slider('SepalLengthCm:', 2.0, 6.0)
SepalWidthCm = st.slider('SepalWidthCm:', 0.0, 5.0)
PetalLengthCm = st.slider('PetalLengthCm',0.0, 3.0)
PetalWidthCm = st.slider('PetalWidthCm:', 0.0, 2.0)
data = {'SepalLengthCm': SepalLengthCm,
'SepalWidthCm': SepalWidthCm,
'PetalLengthCm': PetalLengthCm,
'PetalWidthCm': PetalWidthCm}
features = pd.DataFrame(data, index=[0])
prediction = rf.predict(features)
percentages = rf.predict_proba(features)
st.subheader("Prediction")
st.write(prediction[0])
st.subheader("Percentages")
st.write("Iris-setosa: ", percentages[0][0]*100)
st.write("Iris-versicolor: ", percentages[0][1]*100)
st.write("Iris-virginica: ", percentages[0][2]*100)
Now, to get the requirements.txt (that is necessary for streamlit sharing) I did the following:
conda create --name streamlit-test python=3.7pip install streamlitpip install sklearnstreamlit run streamlit_app.py successfully runs the app locallypip freeze > requirements.txtWhen I deploy the app via Streamlit sharing, it says "ModuleNotFoundError: No module named 'sklearn'" (in line 5). You should actually be able to see this for yourself: https://share.streamlit.io/juliangermek/streamit_test
Checking requirements.txt reveals that sklearn is present like this sklearn==0.0.
This is the log from Streamlit Sharing:

This is my repro with the app in it: https://github.com/juliangermek/streamit_test
I can't figure out why this is working locally, but not with Streamlit Sharing. Do you have any ideas?
Thanks, Julian
Unnecessary packages such as pywin32==300 should be removed from requirements.txt while deploying. This type of package causes errors, so it is better to remove all the unnecessary packages.
Also, it is not sklearn but actually it is scikit-learn. So to install scikit-learn use this line:
pip install scikit-learn
See here
You can also manually change the name of sklearn to scikit-learn by opening requirements.txt file.
scikit-learn==0.22.1
matplotlib==3.2.2
numpy==1.18.1
pandas==1.0.5
streamlit==0.62.0
Werkzeug==1.0.1
