You have missing dependencies!

Mandatory:paramiko > 2.4.0 : None (NOK)

Please install them to avoid this message. Note: Spyder could work without some of thesedependencies, however to have a smooth experiencewhen using Spyder we strong/yrecommend you toinstall all the listed missing dependencies. Failing to install these dependencies might result inbugs. Please be sure that any found bugs are not thedirect result of missing dependencies, prior toreporting a new issue.

Hi @zhu952760029 thank you for the feedback! Seems like your openssl installation is faulty? Could you check what happens when you try to import paramiko from a Python interpreter using an Anaconda prompt? Let us know!

neuralassembly commented 1 year ago

On Tuesday, when I create a new environment on anaconda, the same issue took place (paramiko error when launching spyder).

In such environment, importing paramiko showed the following errors. Therefore, I think that there were some problems on the installation of paramiko or cryptography. (There are no problems in "base" environment.)

ImportError: DLL load failed while importing _openssl: ...

However,when I recreate a new environment on anaconda today, importing paramiko does not show the above errors. I think that the problems on the installation of paramiko or cryptography were fixed.

To fix the problematic environment, the following commands might work, although I have not tried them.

conda install cryptography --force-reinstall or conda install paramiko --force-reinstall

PS: I tried the above command, but they did not fix the problematic environment. Instead, the follwing procedures worked. First, please downgrade the cryptography by conda install cryptography=38.0.4 and then upgrade it by conda install cryptography=39.0.1

Thank you for sharing your findings here @neuralassembly !

dalthviz commented 1 year ago

I will close this as not related with Spyder then but let us know if you find something else!
