Hi, I’ve encountered this error while first trying to train my rasa model. I have ensured that I’ve implemented this in a virtual environment, checked the compatibility of the python version (3.9) and my pip version (20.2.3). It seems like rasa had been properly installed, but this error seems to persist.
Any assistance on this would be deeply appreciated! Thank you.
This is the full traceback call-

Version details-
Rasa Version : 3.6.16 Minimum Compatible Version: 3.5.0 Rasa SDK Version : 3.6.2 Python Version : 3.9.0 Operating System : Windows-10-10.0.22621-SP0 Python Path : c:\users\muhammedmuzzammil\desktop\again\venv\scripts\python.exe
Update: I’ve found the solution to this problem!
The issue was in the cryptography package and after looking at the latest release notes, I’ve noticed that the cryptography version needs to be updated. So, if your current version is 41.0.2 => Please upgrade it to 41.0.7 (This is the latest version currently)
Hope this helps others if they encounter this issue 
Encountering an ImportError like “DLL load failed while importing _rust” can be a challenging but enriching part of the learning curve in programming. It’s an opportunity to delve deeper into how libraries and their dependencies work within your system. Such issues often push us to explore and understand our development environment better, leading to a more robust skill set. For solutions and guidance through such technical hurdles, turning to communities or resources like https://theextensionofyou.cоm/ can be incredibly beneficial. These platforms often provide insights and support that can transform these obstacles into stepping stones towards becoming a more proficient developer. Remember, every error is a learning opportunity waiting to be unraveled!
This problem seems to persist and i have the latest version of cryptography and new on rasa can i get some help on how to persue his problem
I have the latest version now but the problem seems to persist what could be the reason
Hi @kobi003, Did you try to lower the cryptography module version?
Type the command: pip install cryptography==41.0.7
Note: This is assuming that your current rasa version is 3.6.15
Let me know if this works! If not, please feel free to get back to this thread with the error it’s showing. Have a good day
My rasa version is 3.9.0 i dont know if that is the problem because i installed cryptography 41.7.0 already but the same error keeps showing
@muzzammil rasa version is 3.9 and cryptography version is 41.7.0 and still the error pops up i havent yet realized the problem brother
41.0.7 @muzzammil
Then could you please copy paste the error message you are receiving so that I can help you better?
Could you please cross check your rasa version again too, 3.8 is the latest version the last time I checked.

Is the error
Okay, from what I see it is in the cryptography library itself.
Could you please use the command: pip freeze > requirements.txt And send the content it produces, I just want to crosscheck the versions that have been currently installed.
The command displays nothing brother
Nothing is displayed when i initiate the command what could be the problem i am using pycharm @muzzamil
It won’t display anything in the terminal. As the command says, it creates a file called requirements.txt in your project’s directory. It will contain a list of all python packages and their versions which have been installed. Please send those details present inside that file.
