Confirmed working, I made the change manually until committed.

eugeneyng · 2020-08-19T13:34:15Z

I had this issue as well; while we are waiting for the pull request I just wanted to say that my fix was reverting to a previous version of matplotlib

pip uninstall matplotlib
pip install matplotlib==3.1.1

hardikpatel043 · 2020-09-05T09:38:54Z

version 3.2.2 worked for me
pip uninstall matplotlib
pip install matplotlib==3.2.2

shashiHUB · 2020-09-07T15:48:03Z

version 3.2.2 worked for me
pip uninstall matplotlib
pip install matplotlib==3.2.2

I have no luck. Can please tell me what is your python version ? Thx

hardikpatel043 · 2020-09-08T04:30:12Z

version 3.2.2 worked for me
pip uninstall matplotlib
pip install matplotlib==3.2.2

I have no luck. Can please tell me what is your python version ? Thx

My python version is 3.8.5

damonYuan · 2020-10-05T18:17:47Z

can we also update

extras_require={
        'plotting':  ['matplotlib'],
    },

to

extras_require={
        'plotting':  ['matplotlib==3.2.2'],
    },

NSSmithPortfolio · 2020-10-06T12:27:45Z

Python 3.6

zetatez · 2020-10-09T08:28:32Z

+1 to have this PR merged
FWIW, it works on macOS big sur, and it also allows to use matplotlib 4 (version 3.2.2 is not compatible with big sur)

dmiladinovich · 2021-02-06T21:01:00Z

I'll add to this. Your noobies (like myself) are encountering this issue while learning. See the Quick Start guide at the end is a call to cerebro.plot().

I will say, as a noobie, the act of googling this issue, finding the community fix and then joining in on the conversation, was a nice quick start to joining the community as well.

Cheers to staying positive.

ScientiaCapital · 2021-02-06T21:39:11Z

Nice job guys. Noobie here too and can appreciate the community and the support given to the ones that are trying to figure it out.

dvdtth · 2021-03-02T19:32:32Z

when can we expect a new release with this fix in it?

dorak88783 · 2021-03-27T08:55:23Z

A new version would be great - I now can't even run the simplest example without manual workarounds.

ptim · 2021-03-30T13:23:13Z

You can install the merged patch if you specify the commit hash:

pip install git+https://github.com/mementum/backtrader.git@0fa63ef4a35dc53cc7320813f8b15480c8f85517#egg=backtrader

More details: https://stackoverflow.com/a/66871735/2586761

(working for me on python3.9)

GF-Huang · 2021-07-23T14:59:50Z

Why still not release a new version to pip?

Seems not work, still old version.

GF-Huang · 2021-07-23T21:32:29Z

It works after pip uninstall backtrader then reinstall again.

But:

reisenmachtfreude · 2021-07-24T16:17:19Z

Bug is still there. I've uninstalled and installed the module again:
pip3 install backtrader

pip uninstall backtrader

then

pip install git+https://github.com/mementum/backtrader.git@0fa63ef4a35dc53cc7320813f8b15480c8f85517#egg=backtrader

reisenmachtfreude · 2021-07-24T18:44:00Z

@GF-Huang Thank you very much. Like that it works.

cfpavon · 2021-09-23T12:50:27Z

Getting this some bug....while using backtrader from conda installation...

mrx23dot · 2021-10-19T21:34:18Z

Fix ImportError from matplotlib.dates

henke443 · 2022-06-03T12:12:35Z

Why is this still not fixed?

Jay357 · 2022-06-24T12:29:05Z

I've recently started using backtrader.

Python 3.10.5
pip 22.1.2
matplotlib 3.5.2
backtrader 1.9.76.123

Whenever I try to execute: cerebro.plot() This error occurs:
Exception has occurred: ImportError
cannot import name 'warnings' from 'matplotlib.dates' (C:\Users\ [user]\AppData\Local\Programs\Python\Python310\lib\site-packages\matplotlib\dates.py)
File "C:\Users\ [user]\ [folder]\ [folder]\ [folder]\ [folder]\run.py", line 23, in
cerebro.plot()

Is there any workaround at this stage? When is the bug fix coming?

LeMoussel · 2022-07-08T07:01:25Z

The patch is the latest commit to master, but there hasn't been a release.
In the meantime do what is indicated by GF-Huang

You could alternatively specify the required commit in requirements.txt like so:
-e git+https://github.com/mementum/backtrader.git@0fa63ef4a35dc53cc7320813f8b15480c8f85517#egg=backtrader
then pip install -r requirements.txt

rahultandale3 · 2022-07-10T08:54:39Z

Are you implying a solution or workaround to this issue is in the quick start link?

AkiraCharles · 2023-03-22T21:15:24Z

Is there any update on this issue. I'm using:
python- 3.10.10
matplotlib - 3.7.1
backtrader - 1.9.76.123

I cannot download matplotlib==3.2.2 which is one of the suggestions in this thread as a solution.

akosmaroy · 2024-04-23T12:17:23Z

This issue still persists, unfortunately.
