dlerror[s] and Warning messages in keras <- fit.keras(training,testing)

[kozo2]

Hi @PaoloBnn ,

I tried the R commands in https://www.retip.app/ (with Windows 10 and R 4.1.3).

And I got the following errors and warning message in keras <- fit.keras(training,testing).

I would appreciate it if you could let me know if we should care about these messages.

Hi Kozo, this might be an installation error under WINDOWS, which is quite common: https://www.google.com/search?q=dlerror%3A+cudnn64_8.dll+not+found&sourceid=chrome&ie=UTF-8

But try this solution here: error while running fit.keras#9 Tobias

Thank you @tobigithub I noticed that these were warnings, not errors. So I don't care about these messages. I'm sorry for confusing you.

@kozo2 I apologize, many of these issues are due to multiple dependencies. Glad if it will work for you. Tobias
