我在为在线课程安装graphlab时遇到问题。 我已按照论坛中的指示执行以下步骤:
- python -m pip install pip == 9.0.1
- pip install --upgrade --no-cache-dir https://get.graphlab.com/GraphLab-Create/2.1/Email_address/AAA6-B5BC-044E-2F19-79B5-8593-89EC-3C1B/GraphLab-Create-License.tar.gz
- pip install --upgrade pip
- conda安装ipython-notebook
并观看了此视频:https://youtu.be/aXec_IqKA74
但是在运行jupyter笔记本并键入“ import graphlab”时,什么也没有发生。内核抛出错误。
class TicketGUI(QAbstractTableModel):
def __init__(self, data):
QAbstractTableModel.__init__(self)
self._data = data
def rowCount(self, parent=None):
return self._data.shape[0]
def columnCount(self, parent=None):
return self._data.shape[1]
def data(self, index, role=Qt.DisplayRole):
if index.isValid():
if role == Qt.DisplayRole:
return str(self._data.iloc[index.row(), index.column()])
if role == Qt.TextAlignmentRole:
return Qt.AlignCenter
if role == Qt.BackgroundRole:
if self._data.iloc[index.row(), 2] == "In error":
self.setData(self.index(index.row(), index.column()), QBrush(Qt.red), Qt.BackgroundRole) #do not work
#return QBrush(Qt.red) works but color the entire row
有人可以帮忙吗?
谢谢
