I know that others have struggled with this problem, but I don't know what I'm doing wrong. I have installed anything I can see related to gcc, BLAS, or LAPACK in the cygwin packages window, but I still get a long list of errors when I do pip install scipy. I see things like
Running from scipy source directory.
Splitting linalg.interpolative Fortran source files
blas_opt_info:
blas_mkl_info:

NOT AVAILABLE
openblas_info:
libraries openblas not found in ['/usr/local/lib', '/usr/lib', '/usr/lib/']
NOT AVAILABLE
The last error I see is:
Command "/usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip-build-8lzrOH/scipy/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-nzff
hk-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-8lzrOH/scipy
Can someone help me out with this? Numpy is working without any problems.
In Cygwin Setup, install liblapack-devel (openblas will come as dependency). Then you can install scipy with pip install scipy.

I installed Scipy using the command sudo apt-get install python-numpy python-scipy and looks like the latest version of both are installed. But when I try to install a python package named wfdb using pip install wfdb, it get an error while Building wheel for scipy (PEP 517).

`setup.py clean` is not supported, use one of the following instead:

Add `--force` to your command to use it anyway if you must (unsupported).

I upgraded pip using pip install --upgrade pip.
python version used: 3.7
Can I get some help on this?
Clean out the install (I don't know which system you're using) i.e. get rid of the $PATH variables and just do a fresh install.
If you're using Anaconda:
conda install -c anaconda scipy
should do it
also the goops old
pip install scipy
gets it done as well. May I ask why you approached your installation in this way (again, I don't know which system you're on)
Never do sudo pip. Instead do pip install --user. Or (better) work in a virtualenv.
EDIT: typo: there is no space between -- and user.
I've just downloaded the new python 3.8 and I'm trying to install the scipy package using the following:
pip3.8 install scipy
However the build fails with the following error:
**Failed to build scipy**
**ERROR: Could not build wheels for scipy which use PEP 517 and cannot be installed directly**
How can I install this using pip? I tried using the --no-binary version:
pip3.8 install --no-binary :all: scipy
but ended up with an even scarier error:
**ERROR: Command errored out with exit status 1: /Library/Frameworks/Python.framework/Versions/3.8/bin/python3.8 -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/private/var/folders/8p/01_5ykld02v61rtjl8k_8j200000gp/T/pip-install-wlnk_0jg/scipy/setup.py'"'"'; __file__='"'"'/private/var/folders/8p/01_5ykld02v61rtjl8k_8j200000gp/T/pip-install-wlnk_0jg/scipy/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' install --record /private/var/folders/8p/01_5ykld02v61rtjl8k_8j200000gp/T/pip-record-01j_ddt8/install-record.txt --single-version-externally-managed --compile Check the logs for full command output.**
I think I got the same issue as you did. Did the error code have this message
error: library dfftpack has Fortran sources but no Fortran compiler found?
Because to me, it sounds like a Fortran compiler error, and not a mistake of python per se. I think what happens is that the wheel requires some sort of Fortran compiler and when the installation doesn't find one it simply terminates the build. Here is the solution that I found:
Linux
sudo apt install gfortran
Windows / Mac
Download it from here: https://gcc.gnu.org/wiki/GFortran#download
This solution fixed it for me. Check out: Still can't install scipy due to missing fortran compiler after brew install gcc on Mac OS X for more details.
I've been trying the BuildBot First Run tutorial. It starts by creating a master and looks quite simple and straightforward, but I've encountered problems with the step pip install 'buildbot[bundle]'.
I get this error message (this is the end of the log):

I've tried installing mscv build tools, but still get the same message.
Any ideas how I could fix the problem?
Problem is twisted does not yet support python 3.7 (see related issue here: Installing Twisted for Python using pip: error: Microsoft Visual Studio failed with exit status 2).
You can work around this problem by installing precompiled twisted binaries. For example from here: https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted
E.g. in your case download Twisted‑18.9.0‑cp37‑cp37m‑win32.whl and do
pip install Twisted‑18.9.0‑cp37‑cp37m‑win32.whl
Then retry the buildbot install.
pip install 'buildbot[bundle]'
Here is a list of packages I had to install for CKAN 2.7.0
python-setuptools-36.2.4-4.mga7.noarch.rpm
pgdg-redhat96-9.6-3.noarch.rpm
xml-commons git subversion mercurial postgresql96-server postgresql96-devel postgresql96 python-devel libxslt libxslt-devel libxml2 libxml2-devel python-virtualenv gcc gcc-c++ make java-1.6.0-openjdk redis tomcat tomcat-webapps tomcat-admin-webapps xalan-j2unzip policycoreutils-python mod_wsgi httpd tcl-devel redis
after installing these tools i was able to download the git successfully using
pip install --ignore-installed -e git+https://github.com/okfn/ckan.git#ckan-2.7.0#egg=ckan
I then added pgsql-9.6 to the path in order for ckan to recognize pg_config
PATH=$PATH:/usr/pgsql-9.6/bin
Now when I attempt to run the requirements.txt installation it fails with this error
ImportError: No module named pytz
----------------------------------------
Cleaning up...
Command /usr/lib/ckan/default/bin/python -c "import setuptools;__file__='/usr/lib/ckan/default/build/pbr/setup.py';exec(compile(open(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-Aun2rR-record/install-record.txt --single-version-externally-managed --install-headers /usr/lib/ckan/default/include/site/python2.7 failed with error code 1 in /usr/lib/ckan/default/build/pbr
Storing complete log in /usr/lib/ckan/.pip/pip.log
If anybody can explain what the error means and what I need to install/modify I would greatly appreciate it. Seems there is a package called pytz missing but I cannot find information about it.
Thanks
pytz must must installed inside the virtualenv and the pip-requirements-docs.txt must be run prior to running requirements.txt.
I get the following error when attempting to install scipy to PyCharm 3.2:

Note: if you need reliable uninstall behavior, then install
with pip instead of using `setup.py install`:
- `pip install .` (from a git repo or downloaded source
release)
- `pip install scipy` (last SciPy release on PyPI)
Does anyone know how to deal with this?
I am not sure, but you might find your solution in this stackoverflow thread: Can't install Scipy through pip.
If your problem persists, assuming you're on Windows (10), you could try:
Clone library from Github.
git clone https://github.com/scipy/scipy.git
Using CMD, navigate to the scipy folder
cd C:\..(your path)..\scipy
Then install by
python setup.py install
Hope it works out for you!
