pip install numpy --upgrade works, something has to be updated in the files, when you figure out what, could you tell me please, thanks

[xmatthias]

it would appear that numpy is up and downgraded during installation.

The logs during the installation should tell if that's happening - i suspect it's a pinned install-dep version on find_1st (it has numpy as install dependency, so numpy MUST be installed before it's installed).
So if they pin the version on install, but not on run, numpy might be installed twice, first a older version, then a newer one.

[Fusseldieb]

Yup, same problem. Searched for about 2 hours and found nothing...

@Fusseldieb what's your numpy version (pip freeze | grep numpy) ?

after that, please try pip install -U numpy - and post the output of this here (and also if it works after running this).

Thanks for the quick reply!

I did just solve it somehow.

I went into the virtual env and did pip3 install --upgrade numpy

Now it runs ahahaha

[xmatthias]

i guess it's related to the numpy 1.20.0 release.

I suspect that 1.20.0 is installed as build dependency, and later replaced by the pinned version - causing this "compilation conflict".
I'll bump the numpy version in develop soon, that should resolve this.

edit
In my opinion, it's a failure of pip resolution though - as it should recognize that numpy (1.19.5) is beeing installed with the same command, and the build-dependency should therefore be the same.
As consequence of this, i've opened pypa/pip#9542 in hopes to have this fixed in pip.

[emejinglilcompany]

thx for this

[alvarosan]

Thanks for this (https://pypi.org/project/py-find-1st/) fix also @xmatthias . Because of my setup I needed to still build freqtrade against numpy 1.19.5, so bumping py-find-1st to Version 1.1.5 (2021-02-02) fixed my problems.

[neilyoung]

Same issue here out of the blue. I have a requirements.txt for my project, which explicitly requires numpy=1.19.3. Same error as above on a fresh installation (Ubuntu 20.04 on a Banana PI M2Z). Some other module must have required 1.20. After having applied the update command everything works.
Thanks

This is neither related to freqtrade, nor to the problem discussed in this topic.
Please use google / the appropriate support channels for Numpy (or potentially matplotlib) to get help on this topic.

did you find a solution? i'm stuck on the same issue

[xmatthias]

Letme repeat what i said above - this is NOT related to freqtrade - please stop abusing other repositories / issues.
