我正在尝试构建Tensorflow 1.2-rc1，但是如果我尝试使用-mfpu = neon标志进行编译，则构建失败。如果我使用-mfpu = vfpv3标志，那么构建工作正常。这是一个beaglebone黑色基板。有没有人成功地在这种类型的平台上构建它？
Tensorflow来自此提交：https://bitbucket.org/eigen/eigen/commits/f3a22f35b0444e03a1f65941800b9a2283de1398
我收到了构建错误：

正好记录在案，
在/tensorflow/workspace.bzl中 在第147行： 变化：
#Longitude values:
a=0
b=360
prcp = np.load('data.npy')
data=np.average(prcp,axis=0)
plt.figure()
# create Basemap
x1 = np.linspace(a,b, data.shape[1])
y1 = np.linspace(-90, 90, data.shape[0])
xx1, yy1 = np.meshgrid(x1, y1)
data, x1 = shiftgrid(180., data, x1,start= False)
