Question

我在我的Mac上安装了structure(list(HireDate = structure(c(17702, 13242, 16895, 17167, 12335, 13879, 12303, 13745, 14789, 16785, 15390, 17167, 12886, 13472, 15569, 13796, 16811, 11484, 13062, 17592, 16113, 13437, 15614, 17167, 17167, 16251, 17623, 13312, 14165, 17167, 17167, 10695, 15764, 13749, 16801, 17167, 13594, 13874, 17167, 17167, 13157, 17167, 12501, 13243, 12192, 12287, 12965, 13328, 17167, 13343, 17167, 17167, 11839, 17167, 13262, 13326, 14124, 16161, 17167, 17226, 12786, 13823, 13822, 13255, 17704, 17653, 12258, 12769, 13727, 10712, 17400, 13952, 14048, 14333, 17233, 17690, 13108, 13383, 13517, 13829, 17213, 13696, 16741, 17167, 17241, 12198, 14018, 12902, 16801, 17167, 17591, 12843, 13627, 14553, 15593, 16097, 16801, 13075, 13529, 17167), class = "Date"), TermDate = structure(c(NA, 13439, 17712, NA, 12880, 15408, 12877, 16493, 17135, 16944, 17135, NA, 14054, 15670, 17531, 14327, NA, 13889, NA, NA, 16741, 17135, 17620, 17620, 17354, 17316, NA, 13312, 17166, NA, NA, 15705, NA, 15112, NA, NA, 15705, 13970, 17655, NA, 13612, NA, 15418, 15917, 15705, NA, 14274, 13449, NA, 13559, 17417, NA, 14400, NA, NA, 14334, 14813, 16343, 17703, NA, 12824, 15711, 15411, 14484, NA, NA, NA, 15309, 16493, 17197, NA, 14911, 16957, 15882, NA, NA, 14435, 13768, 13517, 14907, NA, 17284, NA, NA, NA, 12772, 17166, NA, 16881, 17439, NA, 14944, NA, 15028, 16581, 16778, NA, 13788, 14064, 17620), class = "Date")), row.names = 14296:14395, class = "data.frame")，该Mac几个月前可以正常工作，但现在无法正常工作了。

我有以下特点。 -OpenCV：3.4.3.1 -操作系统/平台：macOS 10.14 -Python 3.6.5

我尝试在使用opencv的地方重新加载opencv。但是，我收到以下错误消息：

python script

然后，我尝试使用this site的分步说明重新安装opencv，这是我第一次成功安装opencv。

确定我的计算机上装有哪个版本的opencv

写了Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: dlopen(/anaconda3/lib/python3.6/site-packages/cv2.so, 2): Library not loaded: /usr/local/opt/ilmbase/lib/libImath-2_2.12.dylib Referenced from: /usr/local/Cellar/opencv/3.4.1_4/lib/libopencv_imgcodecs.3.4.dylib Reason: image not found和cd /usr/local/Cellar/opencv之后，我得到：ls。因此，我得出结论，我的计算机上的最新版本是3.4.1_4 3.4.3 3.4.3_1

中的3.4.3_1

确定python中包的路径

然后，如果我执行以下/usr/local/Cellar/opencv/3.4.3_1/cv2.cpython-37m-darwin.so和$ cd /usr/local/Cellar/opencv/3.4.3_1，我将会得到$ cd lib。然后，我执行以下操作： python3.7，然后依次是$ cd python3.7和$ cd site-packages，我得到：$ pwd

将cv2..so添加到系统python

我输入/usr/local/Cellar/opencv/3.4.3_1/lib/python3.7/site-packages然后输入python并得到

$ python3

第1个问题，它说版本Python 3.6.5 (v3.6.5:f59c0932b4, Mar 28 2018, 03:03:55) [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin Type "help", "copyright", "credits" or "license" for more information.和opencv似乎有一个lib 3.6.5（而没有3.7）是不是很奇怪？ / p>

键入3.6，然后键入>>> import sys，并获得以下列表：

>>> print(sys.path)

然后输入：

['', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python36.zip', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/lib-dynload', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages']

将OpenCV添加到Virtualenvs

然后添加以下命令：

$ ln -s /usr/local/Cellar/opencv/3.4.3_1/lib/python3.7/site-packages/cv2.cpython-37m-darwin.so /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/cv2.so

此后，应完成安装。但是我仍然收到相同的错误消息

我该怎么办？

Answer 1

实际上opencv已成功安装。

我实际上必须更改jupyter内核的Path文件中的.json。首先，我检查了jupyter内核列表：

$ jupyter kernelspec list
julia-0.6    /Users/mymac/Library/Jupyter/kernels/julia-0.6
julia-1.0    /Users/mymac/Library/Jupyter/kernels/julia-1.0
python3      /Users/mymac/Library/Jupyter/kernels/python3

然后我cd在上面的python路径中，我在里面找到文件kernel.json并打开了它：

{
 "argv": [
  "/path/to/python",
  "-m",
  "ipykernel_launcher",
  "-f",
  "{connection_file}"
 ],
 "display_name": "Python 3",
 "language": "python"
}

然后在该文件中，通过在终端中键入以下内容时获得的python路径更改行/path/to/python：

$ which python
/Users/mymac/anaconda3/bin/python

重新启动Atom，终于成功了！

github page of jupyter的提示也有很大帮助！
