Python pip installieren cvxopt Fehler: Befehl 'C: \\ Programme (x86) \\ Microsoft Visual Studio 14.0 \\ VC \\ BIN \\ x86_amd64 \\ cl.exe' mit Exit-Status 2 fehlgeschlagen

Question

Der Versuch, cvxopt zu installieren mit "pip installieren". Verwenden Sie Window 10, Python 3.6.4 (64-Bit), und haben Sie bereits Microsoft Build Tools 2015 und Visual Studio 14.0 installiert. Ich habe auch das Modul von PyPI ohne Glück direkt heruntergeladen. Benötigen Sie dies für die Optimierung Tutorial so Vorschläge? Dies ist die Befehlszeile:

Answer 1

Wir brauchen die numpy + mkl vor cvxopt installieren, bitte this überprüfen und die numpy + mkl Paket und die entsprechende cvxopt herunterladen, installieren Sie sie wie folgt aus:

1. öffnen CMD und cd auf die Downloads

2. installieren pip „numpy-1.13.1 + MKL-cp36-cp36m Ordner weil einige schwere -win_amd64.whl cvxopt-1.1.9-cp36-cp36m-win_amd64.whl "

Answer 2

cvxopt schwer ist, aus Quellen zu installieren (vor allem auf Windows)“

pip install" Abhängigkeiten (BLAS, LAPACK, SuiteSparse). In Ihrem Fall scheitert es bereits an der einfacheren Abhängigkeit von einigen kompatiblen c-Compiler-Setups.

Lesen Sie die install-docs Sie werden sehen, dass Binärdateien nur für Python 2.7 und Python 3.4 (unter Windows) zur Verfügung gestellt werden!

Verwenden Sie also entweder eine dieser Python-Versionen und machen Sie es erneut, oder verwenden Sie die anaconda-distribution und installieren Sie über Conda-Schmiede wie im obigen Link erläutert. Ich empfehle den Anaconda-Weg! (bearbeiten: keine Windows-Builds in Conda-Schmiede wie im Kommentar erwähnt).

Saras Ansatz basierend auf Gohlkes Binärdateien kann funktionieren. Aber es ist im Allgemeinen schwieriger (wenn es mit anderen Bibliotheken kombiniert wird).

Es gibt auch die aber imho ist es nicht die Mühe wert (und immer noch auf einige Python-Versionen beschränkt).
