QUESTION
i have been using rasa for the past few weeks without problems. But recently i had issues with the installation of Spacy, leading me to uninstall an reinstall python. The issue may have occurred because of some dualities between python3.8 and 3.9 which i wasnt abled to pinpoint.
After deleting all python version from my computer, i just reinstalled python 3.9.2. and reinstall rasa with:

2.4 declares compatibility with Python 3.6, 3.7 and 3.8 but not 3.9 so pip
is trying to find one compatible with 3.9 or at least one that doesn't declare any restriction. It finds such release at version 0.0.5.
To use rasa
2.4 downgrade to Python 3.8.
PS. Don't hurry up to upgrade to the latest Python — 3rd-party packages are usually not so fast. Currently Python 3.7 and 3.8 are the best.

I have exactly the same problem as mentioned in PIP install rasa-x takes forever. In the Rasa installation guide they say, you have to create an environment first. Everytime I do: conda create --name rasa python==3.7.6
it automatically downloads pip-20.3.3. If I now try the pip install --upgrade pip==20.2
command it shows the following error: Error. What did I do wrong? Thanks for the help!
**Update: python -m pip install --upgrade pip==20.2
worked, but now there is another problem when trying to install Rasa-X:Rasa-X installation error
here is the code
...ANSWER
Answered 2021-Jan-25 at 13:34I had this issue as well and for me installing pip packages with python -m pip install
worked. So python -m pip install --upgrade pip==20.2
should work for you.

However, the number of samples in the training set was just about 14 !! which is too small ! and I've just not noticed this difference. I've inverted the training and test datasets, and now, performances are something like this:

Answered 2020-Feb-26 at 14:31Looks like the reason it wasn't working on the server is because the CPU on it doesn't have the AVX instruction set. I have managed to train it on another server that has the AVX instruction set.
QUESTION
i try to install a package sklearn-crfsuite https://pypi.org/project/sklearn-crfsuite/#files on my working computer in windows, where I do not have admin rights. Besides the root enviorment I already created my own enviorment following called: Test.
Normally I use anacando navigator to install new packages, there everything works fine, but this package is not in anaconda navigator, so I am opening the anaconda prompt /conda prompt to install in manually. Here the problem starts.
I start by choosing the right enviorment in the command line:
activate Test
I installed pip and scikit already and have the python version 3.6.8. So I try to run the following command:
pip install sklearn-crfsuite
And I get the error: Could not find a version that satisfies the requirement sklearn-crfsuite Error: no matching distrubation found for sklearn-crfsuite
...ANSWER
Answered 2019-May-17 at 07:44I found a soluation on my own, for everyone who will have this problem at some time, search for the package on anaconda cloud: https://anaconda.org/derickl/sklearn-crfsuite
the command is changing just a little bit then:
conda install -c derickl sklearn-crfsuite
where derickl denotes the cloud.
QUESTION
I am performing NER using sklearn-crfsuite. I am trying to report back on an entity mention by entity mention case as a true positive (both prediction and expected correct even if no entity), false positive (prediction says yes, expected no) or false negative (prediction says no, expected yes).
I cannot see how to get anything other than tag/token based summary statistics for NER performance.
I would be OK with a different way of grouping entity mentions such as: correct, incorrect, partial, missing, spurious. I can write a whole bunch of code around it myself to try to accomplish this (and might have to), but there has to be a single call to get this info?
Here are some of the calls that are being made to get the summary statistics:
...ANSWER
Answered 2019-Mar-22 at 01:01It's not so straightforward to get the metrics you mentioned (i.e., correct, incorrect, partial, missing, spurious) which I believe are the same ones as SemEval'13 challenge introduced.
I also needed to report some results based on these metrics and ended up coding it myself:
- detailed explanation of these metrics
- my own code implementation (it's really too much for a SO post)
I'm working together with someone else and we are planning to release that as package that can be easily integrated with open-source NER systems and/or read standard formats like CoNLL. Feel free to join and help us out :)
QUESTION
I am in the process of migrating a Django app from Heroku to Elastic Beanstalk. It is working fine in Heroku as is.
I am getting the error Your requirements.txt is invalid. Snapshot your logs for details.
When I dive into the eb-activity.log
I see the failure seems to be related to atlas
and scipy
. I don't understand why requirements.txt
is invalid on aws
but valid on heroku
. Insight into what is causing this error and how to remedy would be greatly appreciated.
My eb-activity.log
ANSWER
Answered 2017-Aug-29 at 17:20You need to have a BLAS/LAPACK installed (so that atlas
and atlas-dev
are available on your system). See this link for instructions and try adding libblas-dev
and liblapack-dev
to the yum list of packages in your config file.

Install sklearn-crfsuite
You can use sklearn-crfsuite like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
