Sklearn will not run/compile due to numpy errors - numpy

I would not be posting this question if I had not researched this problem thoroughly. I run python server.py (it uses sklearn). Which gives me
Traceback (most recent call last):
File "server.py", line 34, in <module>
from lotusApp.lotus import lotus

ValueError: numpy.dtype has the wrong size, try recompiling
I next do everything I can, nothing helps.
I ran:
sudo -H pip uninstall numpy
sudo -H pip uninstall pandas
sudo -H pip install numpy
sudo -H pip install pandas
All which give me errors such as OSError: [Errno 1] Operation not permitted:
I try sudo -H easy_install --upgrade numpy
I get a list of errors like
_configtest.c:13:5: note: 'ctanl' is a builtin with type '_Complex long double (_Complex long double)'
_configtest.c:14:5: warning: incompatible redeclaration of library function 'cpowl' [-Wincompatible-library-redeclaration]
int cpowl (void);
^
Edit: Perhaps part of the issue was that I wasn't running the virtual environment. So I get that going, and when I type python server.py, I get error:
from sklearn import datasets
ImportError: No module named sklearn
sudo -H pip install -U scikit-learn Doesn't install because of another error....

I was using depreciated python. I updated everything to python 3, and used pip3.

pipenv installed pip does not work with specified python version

On a Raspberry Pi OS Bullseye system, I tried to install numpy with pipenv using a specific python version and got this:

Looking at the verbose output i see that the path to pip used by pipenv is /home/pi/.local/share/virtualenvs/deep-dregs-eaJke9eC/bin/pip.
Calling this pip directly indeed leads to the same error:
$ /home/pi/.local/share/virtualenvs/deep-dregs-eaJke9eC/bin/pip --version
Traceback (most recent call last):
File "/home/pi/.local/share/virtualenvs/deep-dregs-eaJke9eC/bin/pip", line 5, in <module>

from pip._vendor.packaging.utils import canonicalize_name
ModuleNotFoundError: No module named 'pip._vendor.packaging'
Which python is used in that case? Looking at the shebang line it would seem it's the one I passed to pipenv initially:
$ head -n 1 /home/pi/.local/share/virtualenvs/deep-dregs-eaJke9eC/bin/pip
#!/home/pi/.local/share/virtualenvs/deep-dregs-eaJke9eC/bin/python
$ ls -l /home/pi/.local/share/virtualenvs/deep-dregs-eaJke9eC/bin/python
lrwxrwxrwx 1 pi pi 27 Dec 11 11:00 /home/pi/.local/share/virtualenvs/deep-dregs-eaJke9eC/bin/python -> /opt/python/3.7/bin/python3
But when I explicitly use that exact interpreter there is no error:
$ /opt/python/3.7/bin/python3 /home/pi/.local/share/virtualenvs/deep-dregs-eaJke9eC/bin/pip --version
pip 20.1.1 from /opt/python/3.7/lib/python3.7/site-packages/pip (python 3.7)
The difference seems to be that in the case it goes wrong, the pip installation in /home/pi/.local/share/virtualenvs/deep-dregs-eaJke9eC/lib/python3.7/site-packages/pip is used while in the working case it's the one in /opt/python/3.7/lib/python3.7/site-packages/pip.
But why? My understanding of the shebang is that it points to the interpreter that's to be used. In the working example all i do is call that interpreter explicitly myself. Why is there a difference in behaviour?
And also, why did pipenv even install its own pip in /home/pi/.local/share/virtualenvs/deep-dregs-eaJke9eC/lib/python3.7/site-packages/pip ? Why didn't it reuse the pip that comes with the python version I passed? And if that's just how pipenv works, why is its pip broken? What's going on? And how can I fix it?
EDIT
When i use my system python 3.9 installation it works fine.

I am changing pandas into cudf to make faster aggregating and reduce the processing speed. I figure out one library which works on GPU with pandas.

When trying to install cuDF 0.13, conda is apparently finding a numba version that is incompatible with that cuDF 0.13.
cuDF 0.13 is out of date. The current stable release is 0.17 and the nightly is 0.18. We'll update the README, as it should provide installation instructions for the current version.
We recommend creating a fresh conda environment. Please try the following conda install command, found here:
conda create -n rapids-0.17 -c rapidsai -c nvidia -c conda-forge \
-c defaults rapids-blazing=0.17 python=3.7 cudatoolkit=10.2

Tensorflow Module Not Found Error when running MNIST TPU

I'm new to tensorflow and was trying to follow the tutorial here https://cloud.google.com/tpu/docs/quickstart to run the MNIST TPU model.
I got error from

--model_dir=$MODEL_DIR \
--data_dir=$DATA_DIR \
--train_epochs=10 \

Any idea about to solve it ? Thank you.
You need to install it using command line (or terminal).
pip install --user --upgrade tensorflow-model-optimization
In Google Colab, if you are running a notebook using qkeras you need to do the following:
!git clone https://github.com/google/qkeras.git
import sys
sys.path.append('qkeras')
!pip install git+https://github.com/keras-team/keras-tuner.git
!pip install tensorflow_model_optimization

ImportError: liblapack.so.3gf: cannot open shared object file: No such file or directory

I have both python 2.7.16 and python 3.5.2 installed on my ubuntu 16.04 LTS and numpy used to work well on both of them but recently something went wrong with numpy on python 2 while it still running smoothly on python 3
I have tried to uninstall and install the numpy package and this did not fix anything
The exact stdout I am getting is as follow:
python -c "import numpy as np"

Indeed Linux error while loading shared libraries: cannot open shared object file: No such file or directory resolved the problem. I had have only to do the following:
sudo find / -iname liblapack.so.3gf
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:*path_to_lib_as_found*
sudo ldconfig -v
Thanks to Abdur Rehman for the hint
Cheers.
Does your Ubuntu have the latest lapack library? Try installing sudo apt install liblapack3gf liblapack-dev. Sometimes you need to run sudo ldconfig after the install.

I have this little code:
from numpy import *
from scipy import signal, misc
import matplotlib.pyplot as plt
path="~/pics/"
band_1 = misc.imread(path + "foo.tif");
H = array((1/2.0, 1/4.0, 1/2.0));
signal.convolve2d(band_1.flatten(), H)
plt.figure()
plt.imshow(band_1)
plt.show()
then I execute this code python foo.py and it throws this error:

What is wrong? It seems to be from scipy import signal but I do not know clearly.
I have check another sources and forums but there is no reasons yet:

On Debian, you can use update-alternatives, assuming you have more than reference implementation installed.
From debian wiki
update-alternatives --config liblapack.so.3
update-alternatives --config libblas.so.3
I can't be certain since you didn't specify what distribution you're using, but I ran into the same issue on Gentoo.
/usr/lib and /usr/lib64 have symlinks to the actual libraries. By default, it links to the reference implementation of libblas, libcblas, and liblapack -- which doesn't export symbols for clapack_sgesv, and many other routines.
To resolve this in Gentoo:
sudo emerge blas-atlas
eselect blas list
eselect cblas list
sudo eselect blas set X # Grab X from the result of
sudo eselect cblas set X # the 'list' lines above
sudo emerge lapack-atlas
eselect lapack list
sudo eselect lapack set X
sudo emerge --unmerge scipy numpy matplotlib
sudo emerge scipy numpy matplotlib (... whatever else ...)
I got this problem after an upgrade from Ubuntu 12.04 to 12.10. The problem was that I had two versions of scipy installed in /usr/local/lib/python2.7/dist-packages. To fix the problem I did:
sudo apt-get remove python-scipy
sudo rm -fr /usr/local/lib/python2.7/dist-packages/scipy*
sudo apt-get install python-scipy
