Spyder does not realease memory for matplotlib plots

由 社会主义新天地 提交于 2020-04-11 16:11:22
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 This question already has answers here : Kernel error after updating to Spyder 4.1 (3 answers) Closed 21 days ago . I updated Spyder to version 4.1.0 (together with all other packages in anaconda). Spyder itself works fine however the kernel is not working. I get the following error and can't figure out how to solve it: An error ocurred while starting the kernel The error is: Traceback (most recent call last): File "C:\Users\20172010\AppData\Local\Continuum\anaconda3\lib\site‑packages\spyder

Pandas DataFrames are displaying with new Object Explorer in Spyder 4

由 落花浮王杯 提交于 2020-04-07 06:46:04
问题 I updated Spyder to 4.0.1 which has a new variable explorer, allowing to display arbitrary objects in a tree-like view as well as displaying metadata Previous versions of Spyder enabled to view Pandas Dataframes in a simple table view when double clicking on the variable in the explorer. Is there a simple way of accessing this nice old view in Spyder 4.0.1? 回答1: ( Spyder maintainer here ) You need to have Pandas installed in the same Python installation or environment where Spyder is

问题 Given code like this, how do I actually set a file in the run options? I am using Spyder and have put -h -s -p -o as arguments, but I'm not sure how to specify a named file for the -o option. class CommandLine: def __init__(self): opts, args = getopt.getopt(sys.argv[1:],'hspw:o:') opts = dict(opts) if '-o' in opts: self.outfile = opts['-o'] else: self.outfile = None 回答1: This is a simple tutorial dealing with argpase. But first of all, i recommend you to read the official documentation if you

Spyder 4 Plots Pane Not Displaying

由 狂风中的少年 提交于 2020-03-25 16:06:30
问题 using Spyder 4 which is no longer displaying the Plots pane above the console. I have ensured that the backend is set to Inline but the pane still does not show up. If anyone knows any solutions, it would be greatly appreciated. 回答1: ( Spyder maintainer here ) You need to go the menu View > Panes and activate the entry corresponding to the Plots pane. 来源： https://stackoverflow.com/questions/60287237/spyder-4-plots-pane-not-displaying

KeyError / frozen importlib._bootstrap error on second library import in spyder

由 五迷三道 提交于 2020-03-22 07:09:02
问题 I receive a File " <frozen importlib._bootstrap_external> ", line 978, in _get_parent_path KeyError: 'python_library' error when I import a library from a subfolder the second time in spyder, but the first time (after restarting spyder) or outside of spyder it works fine. The code is: from python_library.tools.test_lib import test_func test_func() where test_lib.py is simply def test_func(): print('Hello!') And the output is: runfile('/home/user/Desktop/test.py', wdir='/home/user/Desktop')
