I have been trying to install matplotlib in a virtual environment using pip.
after working on the virtual environment I tried:
$pip install matplotlib
but I get the error:
unable to execute 'c++' : No such file or directory
error : command 'c++' failed with exit status 1
------------------------------------------
Cleaning up
I am on ubuntu 14.04 and matplotlib works well for me when not using virtualenv, but I would like to have it in a virtualenv for separate projects that I have.
any suggestions?
Solved this problem by just upgrading pip, it seems there was an issue of version 1.5.4 which was installed when creating virtualenv.
$ pip install --upgrade pip
then installed matplotlib using pip
$pip install matplotlib

I am using ubuntu 20.04 with python 3.6.5 Anaconda. Previously, I have installed Tensorflow 2.0.0a0 and it was showing in both "pip list" and "conda list" but Now I want to install version 2.2.0 because I am unable to import "stellargraph" as it requires 2.1.x or higher version But when I uninstalled 2.0.0a0 completely and installing Tensorflow 2.2.0 previously, it was not showing in pip list or conda list and so, again when I am trying to install it on terminal using :
pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow_cpu-2.2.0-cp36-cp36m-manylinux2010_x86_64.whl
as mentioned here, I am getting this output on terminal.
But it is not installed as I can't see it in pip list and site-packages folder.
pip list
Can anyone please help me ?
I have succeed to install Rasa NLU on my Win 10 with python 3.7 but couldn't do this on Ubuntu 18.04.
Please help.
Here is the error I get:
pip3 install rasa-x --extra-index-url https://pypi.rasa.com/simple
Could not find a version that satisfies the requirement
tensorflow~=1.15.0 (from rasa~=1.5.1->rasa-x) (from versions:
1.13.0rc1, 1.13.0rc2, 1.13.1, 1.13.2, 1.14.0rc0, 1.14.0rc1, 1.14.0, 2.0.0a0, 2.0.0b0, 2.0.0b1) No matching distribution found for tensorflow~=1.15.0 (from rasa~=1.5.1->rasa-x)
Please advise what is the difference to my Win10 machine?
Please advise how can I install it.
I had followed these following steps and it's working fine for me for ubuntu 18.04 + Python3
Firstly create directory name of your choice and get inside of it
mkdir rasaprojects #directory name of your choice in place of rasaprojects
cd rasaprojects #get inside that directory
Now create virtual environment of python3
virtualenv rasaenv -p python3 #write your environment name instead of rasaenv
Now activate the environment
source rasaenv/bin/activate
Now you are good to go with rasa installation
pip3 install rasa
Updating your pip version should solve the issue. I believe TensorFlow and your current pip version don't go well together.
Do this:
Download pip installer python script from here.
Run it using python get-pip.py
Another thing is that TensorFlow was not supported by python3.7 untill recently. So if the first solution doesn't work you can try downgrading python to python3.6
Upgrade pip before instaling rasa.
pip3 install --upgrade pip
I'm trying to run this notebook on Google Cloud Datalab: https://github.com/GoogleCloudPlatform/training-data-analyst/blob/master/courses/machine_learning/feateng/feateng.ipynb
While it was perfectly working yesterday, today running the first block results in cffi.error.VerificationError (undefined symbol: SSLv2_client_method).
Can you advise on how I can fix this?
I've tried to do the same from a different GC profile and the problem remains.
I've also tried to fix 'pip install' as described here: pip install fails with "connection error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:598)". Doing this in Datalab causes the same error; doing this in Cloud shell outside Datalab doesn't change anything.
This has been answered on github by #ekuuni:
https://github.com/GoogleCloudPlatform/training-data-analyst/issues/313
%%bash
source activate py2env
conda install -y pytz
conda update -y pyopenssl
pip uninstall -y google-cloud-dataflow
pip install --upgrade apache-beam[gcp]
I needed these 2 more lines for it to work.
pip install tensorflow_transform
pip install tensorflow==1.9.0
A good workaround is using virtual environments rather than Datalab so you don't have to deal with version updates:
https://cloud.google.com/dataflow/docs/quickstarts/quickstart-python
I have successfully installed the following on python 2.7
apache-beam==2.7.0
tensorflow==1.11.0
tensorflow-transform==0.8.0
I can install other packages, but can't install Scrapy. I get the following errors:
warning: build_py: byte-compiling is disabled, skipping.
running build_ext
building 'lxml.etree' extension
error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat).
However, C++ is installed, which I installed numerous of times. I have x86 and 64 bit installations (not sure if it's 10.0) but I have 2013-2017 versions installed.
Please upgrade your pip by following command.
python -m pip install --upgrade pip
Then install Scrapy by following command.
pip install Scrapy
download latest twisted package and install with pip.
https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted
after that install scrapy
In my case, I found that pywin32 was not installed...
So I did
download the latest Twisted package from https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted
You want to use the amd64 if you have Windows 64 (regardless if it's an Intel processor or not)
You can use any browser for the download and copy/paste the file into the project folder of your current pycharm project.
Then in pycharm type this:
pip install Twisted-20.3.0-cp39-cp39-win_amd64.whl
(assuming that your package was Twisted-20.3.0-cp39-cp39-win_amd64.whl)
then proceed with:
pip install Scrapy
I've searched everywhere I could and I couldn't find appropriate answer. I don't know how to install numpy so I could use it in Geany with python 3.1.2. It only works for python 2.6.5. I'm new to ubuntu.
edit: I get ImportError: No module named numpy
If python 3.1.2 is installed via python3 package then you could try:
$ sudo apt-get install python3-numpy
Tried the apt-get installation solution above but it didn't work, however, pip did work:
$ sudo pip3 install numpy
Also, here are the install instructions for pip if needed.
