在 iPython 笔记本的代码单元格中 execution_count 使用什么值?
What value to use for execution_count in code cells of iPython notebooks?
在将 iPython 笔记本生成为 json 文件时,用作 execution_count
的输入参数的最佳值是多少?
我知道它应该设置为 null
但是 json 转储会自动在它周围加上引号,所以我在创建后执行搜索替换并删除它们。然而 ipython notebook 仍然对此不满意。我在 Python 2.7,iPython 笔记本 4.0.5。
import json, fileinput, re
# Create the cell of python code
code_cell = {
"cell_type": "code",
"execution count": "null",
"metadata": {
"collapsed": False,
"autoscroll": False,
},
"source": ["import os\n", "import numpy as np"],
"outputs": [],
}
# Create ipython notebook dictionary
nbdict = { 'metadata': {}, \
'nbformat': 4,
'nbformat_minor': 0,
'cells': [code_cell]
}
with open("test.ipynb", 'w') as outfile:
json.dump(nbdict, outfile)
# Strip double quotes from execution_count argument.
file = fileinput.FileInput("test.ipynb", inplace=True)
for line in file:
print(re.sub(r'"null"', 'null', line))
file.close()
我收到的错误是Notebook Validation failed: Additional properties are not allowed (u'execution count' was unexpected):
即使我在 json 文件中有 "execution count": null,
之后也是如此。
看起来您缺少下划线:"execution count"
应该是 "execution_count"
,然后 null
应该可以正常工作。
