ImportError: DLL 加载失败：找不到指定的程序。 （thinkdsp 和 thinkplot）

Question

I am an amateur programmer. I am trying to use:

import thinkdsp as dsp

import thinkplot as plt

I have installed the pip install thinkx module but I keep getting that error and I don't understand why. I will leave what the console shows down below:

ImportError: DLL load failed: The specified procedure could not be found.

I assumed the issue was with the scipy because all the following errors come from that module. I checked and I have everything installed properly for the scipy module.

Please help! Thank you!

Answer 1

Run any command prompt you are using as administrator and then run pip install lib_name --force-reinstall

Answer 2

Try using these two commands they will help you:

conda remove --force scipy

And:

pip install scipy

Answer 3

Hello I had the same issue than you. Depend on wich version of python you use you should choose a version thinkx. I recommend you to go on the website of thinkx and check out for past udapte. In my case that was with matplotlib 3.3.1 for python 3.7. I went in git bash and used

pip install matplotlib==3.0.1

and everything worked. I had the same issue with seaborn and it worked.
