Problema con scipy install su windows

In precedenza avevo installato scipy, numpy e poi scikit-learn che funzionavano tutti bene. Oggi ho aggiornato tutte le mie librerie con un'installazione di pip. numpy e scikit-learn aggiornati alle ultime versioni, ma scipy ha avuto un problema di compilazione ed è stato ripristinato.Problema con scipy install su windows

Quando provo

from sklearn.ensemble import RandomForestClassifier

ottengo

ImportError: No module named 'format'

ho cercato di risolvere questo problema, ma non ha funzionato per me.

Così, ho disinstallato scipy, in modo che possa reinstallare senza errori. Non sono in grado di farlo.

vedo che le biblioteche Blas e LAPACK sono mancanti. Esiste un modo più semplice per risolvere il mio errore rispetto a dover eseguire dagli installer. Dovrei prendere BLAS, LAPACK, ATLAS per questo.

Qualsiasi input sul motivo per cui ho affrontato questo problema, i file della libreria sono stati eliminati quando ho provato ad aggiornare?

Grazie!

Se si utilizza anaconda, perché non installare scipy utilizzando 'conda install scipy' nella riga di comando? – kikocorreoso

Ho provato l'installazione di conda, continuo a riscontrare problemi come: "ImportError: impossibile importare il nome" check_arrays " – swamoch

Come hai disinstallato scipy? Via pip? Se è stato installato usando anaconda o conda forse hai rotto qualcosa. È possibile reinstallare anaconda? Penso che sarebbe il modo più semplice. Ma prima prova i "Binari di Windows non ufficiali per i pacchetti di estensione Python di Christoph Gohlke" come dice @IVlad. – kikocorreoso

Su Windows, è possibile incontrare problemi se si installa scipy utilizzando pip. Se stai usando anaconda, si può provare ciò che è stato suggerito nei commenti:

conda install scipy

Oppure si può provare a scaricare una versione di Windows di ultima SciPy da here:

Unofficial Windows Binaries for Python Extension Packages by Christoph Gohlke, Laboratory for Fluorescence Dynamics, University of California, Irvine

E quindi utilizzando pip per installare il file .whl scaricato.
