Question

我正在设置张量流，并得到以下输出：

ERROR: matplotlib 1.3.1 requires nose, which is not installed.

所以我在做

sudo easy_install tornado

我得到了输出：

earching for tornado

Download error on https://pypi.python.org/simple/tornado/: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) -- Some packages may not be found!
Couldn't find index page for 'tornado' (maybe misspelled?)
Scanning index of all packages (this may take a while)

我该怎么办？ 谢谢法国的

错误：matplotlib 1.3.1需要鼻子，尚未安装。

似乎您正在代理或防火墙后面运行命令。如果是这种情况，则需要设置相应的环境变量：

set http_proxy="username:password@host:port"
set https_proxy="username:password@host:port"

否则，您可以通过运行tornado使用pip安装--proxy（如果您不在代理后面，则忽略pip --proxy http://user:password@proxy-host:port install tornado）：

sudo -H pip install --ignore-installed matplotlib

编辑：我建议运行

var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera(60, window.innerWidth / window.innerHeight, 1, 1000);
camera.position.set(0, 5, 10);
var renderer = new THREE.WebGLRenderer({
  antialias: true
});
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

var controls = new THREE.OrbitControls(camera, renderer.domElement);

scene.add(new THREE.GridHelper(10, 10, "white"));

var divisions = 100;
var points = [
  new THREE.Vector3(-5, 5, 0),
  new THREE.Vector3(-2, 2, 3),
  new THREE.Vector3(1, 3, 2),
  new THREE.Vector3(3, 5, -3),
  new THREE.Vector3(-3, 4, -2)
];

var curve = new THREE.CatmullRomCurve3(points);
curve.closed = true;
var upperPoints = curve.getPoints(divisions);
var lowerPoints = upperPoints.map(p => {
  return new THREE.Vector3(p.x, 0, p.z)
});
var upperGeom = new THREE.BufferGeometry().setFromPoints(upperPoints);
var lowerGeom = new THREE.BufferGeometry().setFromPoints(lowerPoints);

var cylGeom = new THREE.CylinderBufferGeometry(1, 1, 1, divisions, 1, true); // create an open-ended cylinder
cylGeom.attributes.position.array.set(upperGeom.attributes.position.array, 0); // set coordinates for upper points
cylGeom.attributes.position.array.set(lowerGeom.attributes.position.array, (divisions + 1) * 3); // set coordinates of lower points
cylGeom.computeVertexNormals();

var result = new THREE.Mesh(cylGeom, new THREE.MeshBasicMaterial({
  color: 0xaaaaaa,
  wireframe: true
}));
scene.add(result);


var upperLine = new THREE.Line(upperGeom, new THREE.LineBasicMaterial({
  color: "aqua"
}));
scene.add(upperLine);
var lowerLine = new THREE.Line(lowerGeom, new THREE.LineBasicMaterial({
  color: "yellow"
}));
scene.add(lowerLine);

renderer.setAnimationLoop(() => {
  renderer.render(scene, camera);
});

以安装所需的软件包并忽略当前版本。
