问题 I am currently working on a jupyter notebook in kaggle. After performing the desired transformations on my numpy array, I pickled it so that it can be stored on disk. The reason I did that is so that I can free up the memory being consumed by the large array. The memory consumed after pickling the array was about 8.7 gb. I decided to run this code snippet provided by @jan-glx here , to find out what variables were consuming my memory: import sys def sizeof_fmt(num, suffix='B'): ''' by Fred

问题 I use Spyder 3.3.6, with Pyhton 3.7.3 over IPyhton 7.7.0 cosole. For different reasons, Spyder has always been my IDE of choice, but now I have decided to drop it altogether and stick to command prompt only. The reason is that I have seen a serious memory leak while using matplotlib which is caused by Spyder. Memory increases linearly until all my 128 GB of memory is consumed to the extend that my Ubuntu machine halted completely and I had to hard reset it. I have had this issue in the past

问题 Suppose I've a Jupyter notebook loaded in a browser. Is that possible to somehow run a command line ipython session which connect to the same kernel insance as the one used by the notebook (i.e they can see the same set of variables)? Thanks. 回答1: Yes! After starting/loading an IPython notebook, open up a terminal and connect a command line ipython session using the --existing parameter: jupyter console --existing By default, it will connect to the latest started IPython kernel. To select a

问题 Is it possible to restart an ipython Kernel NOT by selecting Kernel > Restart from the notebook GUI, but from executing a command in a notebook cell? 回答1: As Thomas K. suggested, here is the way to restart the ipython kernel from your keyboard: import os os._exit(00) 回答2: To define a function that restarts the Jupyter kernel, I've successfully used: from IPython.display import display_html def restartkernel() : display_html("<script>Jupyter.notebook.kernel.restart()</script>",raw=True) then

问题 Normally I use R, and often when wanting to make things reproduicible I use sessionInfo() . The reason for this is that I like to let people know what version of everything I am using and what packages I have installed/loaded and what OS I am on etc, so that its quite clear. sessionInfo returns the version of R, the processor type (e.g. 32/64 bit x86), the operating system, the locale details, and which packages have been loaded. I am new to python and wondered if there is an equivalent for
