[image] Pip is taking longer than usual [Deprecated] Rasa X Community Edition Hi I’m trying to install rasa-x on ubuntu 18.04. I created a virtual env. python: 3.6.9 I used the following commands: sudo pip3 install setuptools -U $ sudo pip3 install tqdm -U (virtual env) $ pip3 install rasa-x --extra-index-url https://pypi.rasa.com/simple The process goes well for sometime, then it becomes very slow. An error (INFO: this is taking longer than usual. You might need to prove ide the dependency resolver with stricter constraints to reduce runtime) appears many times and it’… even i m facing same issue please check @rctatman

This helped for me, thanks for the tip @rctatman Maybe this is incorrect but I noticed I have to downgrade the pip version in the respective virtual environment as well. So make sure the virtual environment with rasa is active and: pip install --upgrade pip==20.2 run pip -V to make sure the right version is installed run pip install -U rasa-x --extra-index-url https://pypi.rasa.com/simple Installation time was now quick and under a minute. Without performing these steps I had to wait over an hour and still no result.

It maybe a problem with the latest version of Rasa! I forced the installation to take rasa version 0.34.0 and it worked fine!

It looks like this is being caused by the latest version of pip . A temporary fix is to downgrade your pip version to 20.2: pip install --upgrade pip==20.2

It’s indeed because of the new resolver introduced in the 20.3 release of pip. You don’t need to downgrade your pip version until pip 21.0 is released (that’s when they want to get rid of the old dependency resolver). You can just use the old resolver via --use-deprecated=legacy-resolver like so: pip install --use-deprecated=legacy-resolver --user rasa-x --extra-index-url https://pypi.rasa.com/simple The reason for it takes so much time is the new backtracking feature of the new resolver paired with a not much constrained rasa-x dependencies. They could constrain their deps more to mitigate the issue, but pip probably will do something that fixes these very exaustive installation processes. For more info on the issue, see: python - Resolving new pip backtracking runtime issue - Stack Overflow New resolver downloads hundreds of different package versions, without giving reason · Issue #9215 · pypa/pip · GitHub

When I use your solution I get an error message that the legacy-resolver is unknown. Downgrading pip also didn´t work for my Rasa X installation due to creating loads of conflicts. When I tried to solve one conflict another ten would pop up. Update: I used a lower pip v.20 and python 3.6.10 in anaconda prompt where i created a virtual environment. Installation worked with few conflicts.

first down grade pip and install required packages with downgraded pip

This worked perfectly, thanks! My previous install had been running for 30 minutes and this completed in under 1 minute.

sorry, it has not worked for me i am using python 3.8 on mac-osx i am thinking of using dockerized rasa-x

@raveenb Hello, what you basically want to do or what is your end goal?

i want to share my trained model to my client for a POC. and take feedback from how the users are using the POC and improve the models

@raveenb please share rasa --version?
