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。有人可以帮我编辑此代码以使其正常工作吗？非常感谢！

Answer 1

似乎您正在尝试在普通的Python代码（即不是IPython Notebook）中运行绘图交互功能（i前缀）。 iplot提供了一个交互式图表，您可以在笔记本中进行游戏。

我将从删除iplot导入并将其替换为普通的plot开始。另外，从导入中删除iplot_mpl和init_notebook_mode。

您可以在虚拟环境中安装'ipython'，然后尝试直接从终端运行它。

激活虚拟环境
pip3安装ipython
python3 prog.py

以我的情况工作。

ImportError：`iplot`只能在IPython Notebook中运行
