Pyinstaller无法使用sklearn编译项目

如何解决Pyinstaller无法使用sklearn编译项目

我正在尝试使用sklearn和这些导入来编译这个简单的python 3（pyconda）机器学习项目（这是一个简单的Ridge回归预测器）：

from datetime import date
import pandas as pd
import numpy as np
from sklearn.linear_model import Ridge
 
 
pd.options.mode.chained_assignment = None
 
 
class covidUpdater:
    situazione = ""    
 
    def getCovidUpdate(self):
        url = "https://raw.githubusercontent.com/pcm-dpc/COVID-19/master/dati-andamento-nazionale/dpc-covid19-ita-andamento-nazionale.csv"
        ds = pd.read_csv(url)
        return ds.tail(self.giorni)    
 
    def __init__(self):
        pass
 
 
    def setGiorni(self,giorni):
        self.giorni = giorni
        self.situazione = self.getCovidUpdate()        
 
    def getCampo(self,campo):
        return self.situazione[[campo]]
 
    def getMaxLength(self):
        ur1l = "https://raw.githubusercontent.com/pcm-dpc/COVID-19/master/dati-andamento-nazionale/dpc-covid19-ita-andamento-nazionale.csv"
        ds1 = pd.read_csv(ur1l)
        return len(ds1)
 
    def formatTable(self,campo):
        giorniPrediction = 1
        updater = covidUpdater()
        updater.setGiorni(self.giorni)
        updaterFuture = covidUpdater()
        updaterFuture.setGiorni(self.giorni+giorniPrediction)
        datiCampo = updater.getCampo(campo)
        datiCampoFuture = updaterFuture.getCampo(campo)
        campo_domani = str(campo) + "_domani"
        datiCampo[campo_domani] = datiCampoFuture.shift(-giorniPrediction)
        datiCampo = datiCampo.head(self.giorni-giorniPrediction)
        datiCampo["id"] = range(datiCampo.iloc[:,0].size)
        return datiCampo
 
 
 
 
def main():
    campo = "nuovi_positivi"
    updater = covidUpdater()
    giorni = int(input("Inserisci numero giorni da usare come dataset> ") or updater.getMaxLength())
    updater.setGiorni(giorni)
    print("Giorni selezionati: ",giorni)
    df = updater.formatTable(campo)
 
    print("Imposto l'algoritmo di predizione")
    X = df.iloc[:,0].values.reshape(-1,1)
    Y = df.iloc[:,1].values.reshape(-1,1)
    regr = Ridge(alpha=1.0,normalize=False,tol=0.1,solver="lsqr")
 
    print("Avvio l'algoritmo di predizione")
    regr.fit(X,Y)
    Y_pred = regr.predict(X)
 
    print("-----------------------------------\n")
    print("Giorni in esame: "+ str(giorni)+"\n")
    print("Predizione di (" + str(date.today()) + ") : "+ str(regr.predict(np.array([Y[Y.size-1]])))+"\n")
    print("fattore R2: "+ str(regr.score(Y,Y_pred))+"\n")
    print("-----------------------------------"+"\n")
 
 
if __name__ == "__main__":
   main()

使用此命令：

pyinstaller --noconfirm --onedir --console --hidden-import "sklearn.linear_model.Ridge"  "PATH"

我有此日志，最终错误是：

解决方法

我认为您应该从日志中的第一个错误开始：

set (CMAKE_SYSTEM_VERSION 10.0)

您是否看过这个带有“隐藏的导入”错误的线程？ How do you resolve 'hidden imports not found!' warnings in pyinstaller for scipy?

我认为您需要调整隐藏的导入，以便可以找到'sklearn.linear_model.Ridge'。

我刚刚尝试在Google Colab（https://colab.research.google.com/）中运行您的代码，并且该代码可以在其中运行。也许您可以在其中运行代码？
