QUESTION
The installation on the m1 chip for the following packages: Numpy 1.21.1, pandas 1.3.0, torch 1.9.0 and a few other ones works fine for me. They also seem to work properly while testing them. However when I try to install scipy or scikit-learn via pip this error appears:
ERROR: Failed building wheel for numpy
Failed to build numpy
ERROR: Could not build wheels for numpy which use PEP 517 and cannot be installed directly
Why should Numpy be build again when I have the latest version from pip already installed?
Every previous installation was done using python3.9 -m pip install ...
on Mac OS 11.3.1 with the apple m1 chip.
Maybe somebody knows how to deal with this error or if its just a matter of time.
...ANSWER
Answered 2021-Aug-02 at 14:33Please see this note of scikit-learn
about
Installing on Apple Silicon M1 hardware
The recently introduced
macos/arm64
platform (sometimes also known asmacos/aarch64
) requires the open source community to upgrade the build configuation and automation to properly support it.At the time of writing (January 2021), the only way to get a working installation of scikit-learn on this hardware is to install scikit-learn and its dependencies from the conda-forge distribution, for instance using the miniforge installers:
https://github.com/conda-forge/miniforge
The following issue tracks progress on making it possible to install scikit-learn from PyPI with pip:

Answered 2021-Nov-19 at 13:30It looks like setuptools>=58
breaks support for use_2to3

So you should update setuptools
to setuptools<58
or avoid using packages with use_2to3
in the setup parameters.
I was having the same problem, pip==19.3.1
QUESTION
Background
I have a complex nested JSON object, which I am trying to unpack into a pandas df
in a very specific way.
JSON Object
this is an extract, containing randomized data of the JSON object, which shows examples of the hierarchy (inc. children) for 1x family (i.e. 'Falconer Family'), however there is 100s of them in total and this extract just has 1x family, however the full JSON object has multiple -
ANSWER
Answered 2022-Feb-16 at 06:41I think this gets you pretty close; might just need to adjust the various name
columns and drop the extra data (I kept the grouping
column).
The main idea is to recursively use pd.json_normalize with pd.concat for all availalable children
levels.
EDIT: Put everything into a single function and added section to collapse the name
columns like the expected output.

QUESTION
The following code:
...ANSWER
Answered 2022-Feb-13 at 19:56From the documentation, pandas.DataFrame.drop
has the following parameters:
Parameters
labels: single label or list-like Index or column labels to drop.
axis: {0 or ‘index’, 1 or ‘columns’}, default 0 Whether to drop labels from the index (0 or ‘index’) or columns (1 or ‘columns’).
index: single label or list-like Alternative to specifying axis (labels, axis=0 is equivalent to index=labels).
columns: single label or list-like Alternative to specifying axis (labels, axis=1 is equivalent to columns=labels).
level: int or level name, optional For MultiIndex, level from which the labels will be removed.
inplace: bool, default False If False, return a copy. Otherwise, do operation inplace and return None.
errors: {‘ignore’, ‘raise’}, default ‘raise’ If ‘ignore’, suppress error and only existing labels are dropped.
Moving forward, only labels
(the first parameter) can be positional.
So, for this example, the drop
code should be as follows:

I am trying to set up a conda environment with python 3.10 installed. For some reason, no install commands for additional packages are working. For example, if I run conda install pandas

QUESTION
I have this output :
[Pandas-profiling] ImportError: cannot import name 'ABCIndexClass' from 'pandas.core.dtypes.generic'
when trying to import pandas-profiling in this fashion :
...ANSWER
Answered 2021-Aug-09 at 19:19Pandas v1.3 renamed the ABCIndexClass
to ABCIndex
. The visions
dependency of the pandas-profiling
package hasn't caught up yet, and so throws an error when it can't find ABCIndexClass
. Downgrading pandas to the 1.2.x series will resolve the issue.
Alternatively, you can just wait for the visions
package to be updated.

ANSWER
Answered 2021-Nov-06 at 19:03- The default
pkgs/main
channel forconda
has reverted to usingfreetype 2.10.4
for Windows, per main / packages / freetype. - If you are still experiencing the issue, use
conda list freetype
to check the version:freetype != 2.11.0
- If it is 2.11.0, then change the version per the solution, or
conda update --all
(providing your default channel isn't changed in the.condarc
config file).
- If it is 2.11.0, then change the version per the solution, or
- If this is occurring after installing Anaconda, updating
conda
orfreetype
since Oct 27, 2021. - Go to the
Anaconda
prompt and downgradefreetype 2.11.0
in any affected environment.conda install freetype=2.10.4
- Relevant to any package using
matplotlib
and any IDE- For example,
pandas.DataFrame.plot
andseaborn
- Jupyter, Spyder, VSCode, PyCharm, command line.
- For example,
- An issue occurs after updating with the most current updates from
conda
, released Friday, Oct 29. - After updating with
conda update --all
, there's an issue with anything related tomatplotlib
in any IDE (not justJupyter
).- I tested this in
JupyterLab
,PyCharm
, andpython
from the command prompt. - PyCharm:
Process finished with exit code -1073741819
- JupyterLab: kernel just restarts and there are no associated errors or Traceback
- command prompt: a blank interactive matplotlib window will appear briefly, and then a new command line appears.
- I tested this in
- The issue seems to be with
conda update --all
in(base)
, then any plot API that usesmatplotlib
(e.g.seaborn
andpandas.DataFrame.plot
) kills the kernel in any environment. - I had to reinstall Anaconda, but do not do an update of
(base)
, then my other environments worked. - I have not figured out what specifically is causing the issue.
- I tested the issue with
python 3.8.12
andpython 3.9.7
- Current Testing:
- Following is the
conda
revision log. - Prior to
conda update --all
this environment was working, but after the updates, plotting withmatplotlib
crashes the python kernel
