I would like to import files from a few packages which are #openzeppelin/contracts/utils/math/Math.sol, #uniswap/v2-periphery/contracts/interfaces/IUniswapV2Router01.sol, and #uniswap/v2-core/contracts/interfaces/IUniswapV2Pair.sol. I have installed all the relevant packages using npm install [package-name] -g so I assume that the package is available on my laptop. Nonetheless, I still received this error message after running the truffle compile command. How do I import these files to use them in my .sol files?

I am unable to import yfinance or multitasking. I used pip install yfinance and it downloaded and installed everything but I got this message regarding yfinance and multitasking. I am using Spyder and it is unable to import these 2 but able to import everything else.
Using legacy 'setup.py install' for yfinance, since package 'wheel' is not installed.
Using legacy 'setup.py install' for multitasking, since package 'wheel' is not installed.

Python appears to be unable to locate the module QAxContainer in PyQt5. The package was installed using Conda and is present in a sub-directory of PyQt5 but cannot be located. Additional testing with pip resulted in the same error.
Ubuntu 20.04
Python 3.8.5
conda list
pyqt5 5.15.2 pypi_0 pypi
from PyQt5 import QAxContainer
ImportError: cannot import name 'QAxContainer' from 'PyQt5' (/home/brian/anaconda3/lib/python3.8/site-packages/PyQt5/init.py)
However, qaxcontainer.py is present in /home/brian/anaconda3/lib/python3.8/site-packages/PyQt5/uic/widget-plugins
There should be QAxContainer.pyd and QAxContainer.pyi at /home/brian/anaconda3/lib/python3.8/site-packages/PyQt5/. If you dont have them maybe there's a problem with the package, try reinstalling PyQt5.
According to antonio2924, QAxContainer.pyd and QAxContainer.pyi should be located at /home/brian/anaconda3/lib/python3.8/site-packages/PyQt5/. The .pyd file extension is specific to Windows. Furthermore:
The QAxContainer module is a Windows-only extension for accessing
ActiveX controls and COM objects. See, https://doc.qt.io/qt-5/qaxcontainer-module.html
I am running Ubuntu 20.04, which explains why QAxContainer is not being installed.
my setup.py is like below:
from setuptools import find_packages, setup
tests_require = ['pytest-env', 'pytest-mock', 'pytest-cov', 'pytest-xdist', 'pytest', 'mock', 'moto<=1.3.10']
setup(

)
When I run python setup.py test, it will always reinstall the most of the packages that I already installed into .eggs folder, which I understand. While it's installing the package with different versions that I provided in the install_requires section, which results in below error:
pkg_resources.ContextualVersionConflict: (urllib3 1.25.10 (/Users/***/Desktop/repo/.eggs/urllib3-1.25.10-py3.7.egg), Requirement.parse('urllib3<1.25,>=1.21.1'), {'requests'})
I have to pin the requests version to 2.22.0 which requires urllib3 version no larger than 1.25, which caused my issue. So, is there anyway I can pin the urllib3 version in somewhere so when it runs, it will only install the provided version? I have tried to add the urllib3 version in install_requires, tests_require and in requirements.txt, but no luck so far.
Probably not what you want to hear but... setup_requires and tests_require are deprecated. Although they (probably) still work (mostly) fine, you might want to look for alternative solutions. As far as I know the most common alternative solutions are to use Tox instead of tests_require and PEP 517 to replace setup_requires.
In your case, it seems that your usage of setup_requires is only a consequence of your usage of tests_require. So by switching to something like Tox you get rid of both tests_require and setup_requires.
I got it resolve to simply replace python setup.py test to be pip instll -e . [test], and then pytest directly.
It will still install all the tests_require packages and then run pytest directly. Instead of going through all the list packages and find the best match versions for all packages.
UPDATES:
The real problem is I did not remove the old .eggs/ and venv/ folder when I made the packages version change. So the solution is updating the requests version to be 2.21.0 in the setup.py file, then remove the .eggs/ and venv/ folder and rerun everything.
The version of my Python is 2.7.13.
I run the following in Jupyter Notebook.
Firstly, I installed the packages
%%bash
pip uninstall -y google-cloud-dataflow
pip install --upgrade --force tensorflow_transform==0.15.0 apache-beam[gcp]
Then,
%%bash
pip freeze | grep -e 'flow\|beam'
I can see that the package tensorflow-transform is installed.
apache-beam==2.19.0
tensorflow==2.1.0
tensorflow-datasets==1.2.0
tensorflow-estimator==2.1.0
tensorflow-hub==0.6.0
tensorflow-io==0.8.1
tensorflow-metadata==0.15.2
tensorflow-probability==0.8.0
tensorflow-serving-api==2.1.0
tensorflow-transform==0.15.0
However when I tried to import it, there are warning and error.
WARNING:tensorflow:From /usr/local/lib/python2.7/dist-packages/tensorflow_estimator/python/estimator/api/_v1/estimator/__init__.py:12: The name tf.estimator.inputs is deprecated. Please use tf.compat.v1.estimator.inputs instead.
ImportErrorTraceback (most recent call last)

1 import tensorflow as tf
----> 2 import tensorflow_transform as tft
3 import shutil
4 print(tf.__version__)
ImportError: No module named tensorflow_transform
After some investigation, I think I have some ideas of the problem.
I run this:
%%bash
pip show tensorflow_transform| grep Location
This is the output
Location: /home/jupyter/.local/lib/python3.5/site-packages
I tried to modify the $PATH by adding /home/jupyter/.local/lib/python3.5/site-packages to the beginning of $PATH. However, I still failed to import tensorflow_transform.
Based on the above and the following information, I think, when I ran the import command, it executes Python 2.7, not Python 3.5
import sys
print('\n'.join(sys.path))
/usr/lib/python2.7
/usr/lib/python2.7/plat-x86_64-linux-gnu
/usr/lib/python2.7/lib-tk
/usr/lib/python2.7/lib-old
/usr/lib/python2.7/lib-dynload
/usr/local/lib/python2.7/dist-packages
/usr/lib/python2.7/dist-packages
/usr/local/lib/python2.7/dist-packages/IPython/extensions
/home/jupyter/.ipython
Also,
import sys
sys.executable
'/usr/bin/python2'
I think the problem is tensorflow_transform package was installed in /home/jupyter/.local/lib/python3.5/site-packages. But when I run "Import", it goes to /usr/local/lib/python2.7/dist-packages to search for the package, rather than /home/jupyter/.local/lib/python3.5/site-packages, so even updating $PATH does not help. Am I right?
I tried to upgrade my python, but
%%bash
pip install upgrade python
Defaulting to user installation because normal site-packages is not writeable
Then, I added --user. It seems that the python is not really upgraded.
%%bash
pip install --user upgrade python
%%bash
python -V
Python 2.7.13
Any solution?
It seems to me that your jupyter notebook is not using the right python environment.
Perhaps, you installed the package under version 3.5,
but the Notebook uses the other one, thus it cannot find the library
You can pick the other interpreter by clicking on: Python(your version) - bottom left.
VS-Code - Select Python Environment 1
However you can do this also via:
CNTRL+SHIFT+P > Select Python Interpreter to start Jupyter Server
If that does not work make sure that the package you are trying to import is installed under the correct python environment.
If not open up a terminal, activate the environment and install it using:
pip install packagename
For example i did the same thing here: (Note: I'm using Anaconda)
installing tensorflow_transform
After a installation, you can import it in your code directly like this:
importing tensorflow_transform
I was trying to clone and install the Google Unrestricted adversarial examples repository following the instructions provided here. But I am unable to import the any of the modules. First I cloned the repository and changed to that directory.
!git clone https://github.com/google/unrestricted-adversarial-examples.git
cd unrestricted-adversarial-examples
Then I used the pip install command.
!pip -e install bird-or-bicycle
The installation completed without any error. However, when I try to import I get the 'module not found error'. Could anyone tell me what I am doing wrong? I tried the same commands on my PC and it works.
import bird_or_bicycle
ModuleNotFoundError: No module named 'bird_or_bicycle'
I just got the solution after posting an issue to the repository. The solution was simple, all I needed to do was restart the Colab kernel (Restart Runtime option in the Runtime tab) after !pip -e install bird-or-bicycle Apparently that is required to pick up the newly installed package.
If you look at the bird-or-bicycle docs, you see that there is a data download step required after you pip install.
If you follow the instructions there and run the following in a notebook cell, then the import will work:
!git clone https://github.com/google/unrestricted-adversarial-examples
!pip install -e unrestricted-adversarial-examples/bird-or-bicycle
!bird-or-bicycle-download
