I'm kind of new to Scipy and IronPython, so please excuse any dummy question I might be asking.
Anyway, I'm trying to upgrade my scipy version to >1.1 on my IronPython 2.7.5 (OS is Windows 7 64bit) but I am not really sure how to do it.
My current scipy version is 1.0.0.
I've tried to run from command prompt:
ipy -X:Frames -m pip install --upgrade scipy
But I'm getting this:
Downloading/unpacking scipy
C:\Program Files (x86)\IronPython 2.7\lib\site-packages\pip\_vendor\requests\packages\urllib3\connectionpool.py:1: DeprecationWarning: object.__new__() takes no para
meters
# urllib3/connectionpool.py
Cannot fetch index base URL https://pypi.python.org/simple/
Could not find any downloads that satisfy the requirement scipy
Cleaning up...
No distributions at all found for scipy
Any help on how to get it to work will be appreciated. Alternatively, if there are other ways to easily install newer compiled version of scipy on IronPython env, it's also OK - I just need to know.

i need to download librosa to raspberry pi so first of all i downloaded virtualenv and created environment and installed llvm with:
sudo apt-get install llvm
pip3 install llvmlite==0.37
pip3 install librosa=0.6.3
then tried to import a librosa in abc.py file. execution output is:
importerror-numpy-core-multiarray-failed-to-import
changing the numpy version didin't help output evolved:
numba 0.55 requires numpy 1.22
tried to change numba version but it didin't help either
anyway...
everyone installed llvm version 7 for librosa but my version is 11. I couldn't find the download with version. I've tried:
sudo apt-get install llvm-7.0
Librosa and numpy does not work well in llvm11.
how can i download version 7?
Thanks for advices
How to install TensorFlow on Python 3.7
Trying:
D:\Users\Downloads>pip install tensorflow
ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none)
ERROR: No matching distribution found for tensorflow
Windows 10 OS
And with vent error, too
(venv) C:\Users\KvaksManYT>pip install --upgrade tensorflow
ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none)
ERROR: No matching distribution found for tensorflow
I would recommend using a virtual environment using pip install vitualenv. Then, depending on your OS, you want to create and activate an environment.
python3 -m venv /path/to/new/virtual/environment
Then, activate this environment using,
source ./venv/bin/activate
Now, you can install any Python packages you want.
pip install tensorflow==2.0.0
you can install Tensorflow follow those steps
Ubuntu/Linux /mac os /windows
virtualenv does not require a mention pip version
for system install, you need to mention pip version
upgrade pip version
pip install --upgrade pip
#virtualenv install
pip install --upgrade tensorflow
#system install
pip3 install --user --upgrade tensorflow
reference https://www.tensorflow.org/install/pip
I had the same problem with Windows 10 x64, and it was caused because I was using the wrong Python version, both globally and in the venv. I found questions on the issue multiple times on the internet, including yours.
Be sure to use Python versions 3.5-3.8, as per requirements, but also x64, not x32.
Namely, I ran into this error using both
a venv with 3.9.1 x64 (python --version),
and my globally installed 3.8.2 x32 (python3 --version).
So, I downloaded the x64-version of Python 3.8.6 from here.
Note that the command venv does not allow specifying the python version used in the virtual environment,
as per an answer on this question. So I used virtualenv, which I obviously had to install in my global Python version first.
To specify the Python version used in the venv, I used the command virtualenv, as in:
virtualenv --python="C:\Users\me\AppData\Local\Programs\Python\Python38\python.exe myvenv
where you have to give the path to the newly downloaded Python distribution you want to use, if there are several on your PC (for example, I had Python38-32 and Python39 folders in that directory).
Check Python versions in virtual environment
After I activate my myvenv, created as above, I verify the Python versions as follows:
python3 --version
> Python 3.8.2
python --version
> Python 3.8.6
Then, using the command
import struct
print(struct.calcsize("P") * 8)
Within either python3 or python, shows me whether the version is 32bit or 64bit, as per this answer. The python returns a 64, so that is the one you want to use (not python3).
Finally, within the virtual environment, you can run
pip install --upgrade tensorflow
and it will download and install. (Meanwhile, pip3 install --upgrade tensorflow would still return your error inside and outside the virtual enviroment.)
When trying to import SkewT into my python3 code on a Mac (Mojave 10.14.6):
from metpy.plots import SkewT
I get the error:

pip3 install cartopy gives the output

To start, I tried to install Proj and geos, but pip3 only lists version 0.1.0 for proj and 0.2.2 for geos. Before I get too far down this rabbit hole, I thought I'd see if anyone else has encountered this problem. Thanks!
So it looks like MetPy 0.10 accidentally picked up a hard dependency on CartoPy, which we did not really plan. You can track our resolution of that here.
CartoPy depends on a lot of compiled libraries that are not pip-installable unfortunately. Your best bet is to look at CartoPy's install instructions. If you're using Anaconda or Canopy, those distributions have pre-built CartoPy packages available.
One option to work around this is to install MetPy 0.9:
pip install metpy==0.9
Do you use Conda? The easiest way to remedy this problem is to install CartoPy (or MetPy for that manner) via conda, so that all of the right dependencies are also downloaded: conda install -c conda-forge cartopy or conda install -c conda-forge metpy. Pip doesn't bring all of them together, so that leads to this problem being raised.
Thanks. Without conda, I was also able to complete this (more painful) installation:
- brew install geos
- brew install proj
- pip3 install cython
- pip3 install git+https://github.com/SciTools/cartopy.git#master

I have noticed a number of similar questions on stackoverflow, but none that really helped me with my current challenge. I have been attempting to install eric6 on my Raspberry Pi setup. And then I encountered the following messages:
Checking dependencies
Python Version: 3.6.8
PyQt5 could not be detected.
Error: No module named 'PyQt5.sip'
Shall 'PyQt5' be installed using pip? (Y/n) Y
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Requirement already satisfied: PyQt5 in /usr/local/lib/python3.6/site-packages (5.12)
Sorry, please install PyQt5.
Error: No module named 'PyQt5.sip'
And when I attempt to use the pip list to look at what has been installed (as I previously already managed to make and install the PyQt5 from source code):
Package Version
---------- -------
pip 19.0.3
PyQt5 5.12
setuptools 40.6.2
sip 4.19.14
So, how do I overcome the issue that I am currently facing? By the way, I am using the following command when attempting to install eric6:
python3 install.py
Thought you might need to know that if it helps.
Python 3.6 isn't available in any Raspbian distribution, so I assume you installed this yourself. You can't install an out-of-distribution Python version and expect distribution Python packages to work. You have PyQt5 installed, yes, but it's the version of PyQt built for Python 3.5 (I'm assuming you're on Raspbian Stretch).
Sometimes you can install Python libraries with pip, and in theory that could work to install the correct version of PyQt for your version of Python, but PyQt only provides wheels for x86 on PyPI, not for Arm, so PyQt is not pip installable on the Pi. The only way to get PyQt on Raspberry Pi is via apt, where your choices are Jessie (old stable - with Python 3.4), Stretch (current stable - with Python 3.5), and Buster (unstable/testing - with Python 3.7). If there's a need for Python >3.5, your best bet is to try upgrading to Buster, but bear in mind it's not ready for release yet.
I am trying to install numpy to use within plpython3u in postgres 9.6 for
Windows 2012 (64 bit) but I run into dependency problems.
1) I have installed Postgres 9.6 from EnterpriseDB and the language pack,
which automatically installs Python 3.3. <- is there a way to install a newer version of Python?
I have done CREATE EXTENSION plpython3u; and it works correctly.
I tried to install python modules with: pip3.exe install numpy and
python -m pip install --user numpy but numpy-1.12.1 returns an error:
raise RuntimeError("Python version 2.7 or >= 3.4 required.")
If I try to install an older version of numpy==1.10.4, there are a number
of errors about blas and atlas and fortran compilers not being available -
so I didn't pursue that avenue much further.
2) If I install Python 3.6 separately, when CREATing EXTENSION plpython3u,
I get the
ERROR: could not load library "C:/Program
Files/PostgreSQL/9.6/lib/plpython3.dll": The specified module could
not be found.
The DLL is in that location, but the utility "depends" shows that it is
compiled for python33 and not python36, and those dependencies are
missing. Could I replace the plpython3.dll file somehow to get it to work
with Python 3.6?
Surely someone has installed numpy for plpython3u in postgres for Windows,
but I could not find any solutions so far..
Thanks
Peter
