导入错误：`iplot` 只能在 IPython Notebook 中运行

Question

当我在 Mac 上的 PyCharm 中运行以下代码时？

import numpy as np 
import pandas as pd 

from subprocess import check_output
print(check_output(["ls", "../input"]).decode("utf8"))


import time
import copy
import numpy as np
import pandas as pd
import chainer
import chainer.functions as F
import chainer.links as L
from plotly import tools
from plotly.graph_objs import *
from plotly.offline import init_notebook_mode, iplot, iplot_mpl
init_notebook_mode()
data = pd.read_csv('../input/Data/Stocks/goog.us.txt')
data['Date'] = pd.to_datetime(data['Date'])
data = data.set_index('Date')
print(data.index.min(), data.index.max())
data.head()

有一些错误：

UserWarning: Accelerate has been detected as a NumPy backend library.
vecLib, which is a part of Accelerate, is known not to work correctly with Chainer.
We recommend using other BLAS libraries such as OpenBLAS.

我是 Chainer 和 DQN 的新手。谁能帮我编辑此代码以使其正常工作？非常感谢！

似乎您正在尝试i在普通 Python 代码（即不是 IPython Notebook）中运行情节交互函数（前缀）。iplot提供了一个交互式图形，您可以在笔记本中使用它。

我首先删除iplotimport 并将其替换为 normal plot。此外，从您的导入中删除iplot_mpl和init_notebook_mode。
