Pytorch, pipenv and numpy support?

I am using pytorch and installed it follow these instructions:

pipenv install git+https://github.com/pytorch/pytorch#egg=pytorch
pipenv install git+https://github.com/pytorch/vision#egg=torchvision

in order to install pytorch with pipenv. This runs some of the examples, but for instance, this MNIST code:

from __future__ import print_function
import argparse
import torch
import torch.nn as nn
import torch.nn.functional as F
import torch.optim as optim
from torchvision import datasets, transforms
from torch.autograd import Variable

                    help='input batch size for training (default: 64)')
parser.add_argument('--test-batch-size', type=int, default=1000, metavar='N',
                    help='input batch size for testing (default: 1000)')
parser.add_argument('--epochs', type=int, default=10, metavar='N',
                    help='number of epochs to train (default: 10)')

                    help='SGD momentum (default: 0.5)')

                    help='disables CUDA training')
parser.add_argument('--seed', type=int, default=1, metavar='S',
                    help='random seed (default: 1)')

Does not run giving the error:

RuntimeError: PyTorch was compiled without NumPy support

Running:

pipenv install numpy

does not resolve the error. Is there a way to use pipenv and install pytorch with numpy support?
