How to deal with ImportError: cannot import name 'pytree' from 'jaxlib' of using jax?

I have installed jax and jaxlib using pip according to https://github.com/google/jax#installation:
Successfully installed jax-0.1.68 jaxlib-0.1.67+cuda11
But after i ran my project, it showed Importerror:
Traceback (most recent call last):

from jaxlib import pytree
ImportError: cannot import name 'pytree' from 'jaxlib' (/home/control/.local/lib/python3.7/site-packages/jaxlib/__init__.py)
Could this problem comes from uncompatible jax/jaxlib version for running the project?
If not, how to deal with it?

It appears that you are importing a much older jax version than you report in the question; jax.lib has not attempted to import pytree from jaxlib since version 0.2.8.
This probably indicates that you are running pip install in a different environment than the one you're using to execute code.
Assuming you are working at the command prompt, try this instead:
$ python -m pip install jax jaxlib
$ python -c "import jax; print(jax.__version__)"
(where you can replace python in both lines with whatever python executable you are using)

Version conflict between cvxpy and numpy: "module compiled against API version 0xe but this version of numpy is 0xd"

I'm trying to upgrade some packages and to consolidate my requirements.txt for an existing python program in order to move it to a docker container.
This container will be based on the tensorflow docker container, this dictates some package versions I have to use. We work under windows and we want to be able to run the program locally on our machines (at least for some time). So I need to find a configuration that works in docker and on Windows 10.
Tensorflow 2.4.1 needs numpy~=1.19.2. When using numpy 1.20, pip complains that numpy 1.20 is an incompatible version.
But when using numpy~=1.19.2 I get the following error when importing cvxpy. pip installs all packages just fine:
RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd

import _cvxcore
ImportError: numpy.core.multiarray failed to import
Steps to reproduce:
1.)
Create a new Python 3.8 venv under Windows 10 and activate it
2.) Install the following requirements.txt via pip install -r requirements.txt:
cvxpy
numpy~=1.19.2 # tensorflow 2.4.1 requires this version
3.) Execute the following test.py via python test.py
import cvxpy
if __name__ == '__main__':
pass
The same thing happens if I want to use tensorflow 2.3. In this case numpy~=1.18 is needed, the error is exactly the same.
Searching for the error finds very few hits which sadly did not help me.
What can I do to solve this?

SKlearn importError

Hi just updated my version of python from 3.7 to 3.8 I am using pycharm IDE and sklearn was working perfectly fine in the previous version but now when I try to run code that was
However after updating my version it keeps giving the following error.

I have made sure that the interpreter is correct. I have made sure that I have uninstalled older versions of python from my computer but unfortunately still no luck.
I will really appreciate it if someone can point out how to solve this problem.
Thanks

Try removing Scipy folder from C:/Users/SmithyB/AppData/Roaming/Python/Python36/site-packages/scipy
Reinstall using pip install scipy

Thanks for all your input, I couldn't have solved the problem without you guys.
I am posting how I solved the problem with the hope that it will be helpful to someone.
Since the problem was originally with using the SK-Learn library I uninstalled scikit-learn
pip uninstall scikit-learn
and then reinstalled it.
pip install scikit-learn
the error did not go away after that so I followed the suggestion of uninstalling scipy
pip uninstall scipy
and then reinstalling it.
pip install scipy
I ran a code that I had written which uses sklearn previously and it worked.

Can't import audiolab in python

I installed audiolab from this source:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#scikits.audiolab
Those are the only windows binaries for python 2.7 I was able to find.
When I call from scikits import audiolab I get the following error:
Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
from scikits import audiolab

NameError: _SNDFILE_FILE_FORMAT
Is there a way to fix it? If not what should I use for audio processing instead? (Audiolab seemed to be the best alternative among audiotools and pyaudio)
EDIT:
After replacing libsndfile-1.dll, I have this new error:
Traceback (most recent call last):

Note: numpy is installed.

As far as I can tell you need to install libsndfile-1.0.25 as is mentioned right where you downloaded the binary
Scikits.audiolab is a package for audio file IO using numpy arrays. Linked against libsndfile-1.0.25.
You can download an installer from here. You may need to reinstall the scikits.audiolab distribution after you install libsndfile (although honestly, I'm not sure).
However, if this seems a lot of effort, it might be easier for you to install Python 2.6 and install audiolab from PyPi as scikits docs suggest. The PyPi version of scikits.audiolab is statically linked to libsndfile so you will not need to install it on your own.

I had the same problem on Mac OS. It's possible that you updated or installed a new version of python/numpy after you install audiolab. What I did is uninstall scikits.audiolab and reinstall it again, which got rid of this error

I had the same problem on Ubuntu 10.04.4 LTS. The reason was that the installed version of audiolab was for python2.5, but in the meantime with Ubuntu 10.04.4 LTS python was upgradee to version 2.6. After a new install of audiolab (wich grabbed the correct version) all's working fine.

All you need to do is to install libsndfile would have worked also.
brew install libsndfile

Installing numpy broke NLTK (OS X 10.6.2, Python 2.6)

I had a working installation of NLTK (py26-nltk) on my Mac (OS X 10.6.2). Then I installed numpy. Now when I try to import nltk, I get this:
>>> import nltk

ValueError: numpy.dtype does not appear to be the correct type object
What has gone wrong? How can I fix this?

It seems to be more of a matter of [version] incompatibility between SciPy and NumPy versions than between NLTK and Numpy.
While SciPy is not required for NLTK, it is an optional import, and will load if available.
A few hypothesis regarding your situation:
Hyp #1
you formerly were running under NumPy 1.3 along with a compatible version of SciPy
you recently installed NumPy 1.4 but didn't touch SciPy
==> "Old" SciPy is broken.
Remedy : Install newer SciPy or uninstall it altogether (although you may be using/needing SciPy, without knowing it, depending on the modules of NLTK you use)
Alternate Remedy: re-install NumPy 1.3 over 1.4.
Hyp #2 (less likely)
You never had SciPy and NLTK was happy, working without it.
You recently installed NumPy 1.4 (over 1.3) and SciPy (over nothing)
For some reason NumPy and SciPy don't play nice together
Remedy: Uninstall SciPy

I had the same problem on Python 2.6 on Windows XP and as suggested by mjv, I uninstalled my old SciPy module and installed the latest, at which stage I got the error that the yaml module was missing.
After installing the PyYAML module, the "import nltk" statement didn't give any errors.
Hope this helps anyone else having the same problem.

Chiming in somewhat late, but I ran into this problem with numpy and fisher, on osx (snow leopard,
but I assume this would happen on other x86 machines).
I had installed fisher via pypm, and installed numpy from a binary dmg. In a situation
like this I assume that somewhere along the way a binary got infected with a PowerPC
binary, so it's best to clear them away, and rebuild from source.
I manually deleted them from ~/Library/...,
pulled down the sources (including scipy, might as well bite that bullet now),
recompiled all three from source, and two hours later had a working system.
